Pulling out like terms
3.1 Pull out like factors :
8g2 - 10g - 12 = 2 • (4g2 - 5g - 6)
Trying to factor by splitting the middle term
3.2 Factoring 4g2 - 5g - 6
The first term is, 4g2 its coefficient is 4 .
The middle term is, -5g its coefficient is -5 .
The last term, "the constant", is -6
Step-1 : Multiply the coefficient of the first term by the constant 4 • -6 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -5 .
-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 3
4g2 - 8g + 3g - 6
Step-4 : Add up the first 2 terms, pulling out like factors :
4g • (g-2)
Add up the last 2 terms, pulling out common factors :
3 • (g-2)
Step-5 : Add up the four terms of step 4 :
(4g+3) • (g-2)
Which is the desired factorization
Final result :
2 • (g - 2) • (4g + 3)

Amanda wants to buy a new iPod that costs $250. When she gets to the Apple store
she sees they are having a sale for 15% off all iPods. She also has a coupon that takes
an additional 15% off the discounted price. What is the final cost of the iPod? (multi
step problem) (first you need to find the price when you take 15% off, and then you
take an additional 15% off of the discounted price)
Answer:
Answer:
15% off 212.5
30% off 175$
Step-by-step explanation:
15+15=30 so
250/100=2.5
2.5x30=75
250-75

Rectangle JKLM is shown. What is the value of x?
11 12 13 14 15
A rectangle has an area of (x2 − 17x + 72) square units. Since the area of a rectangle is determined using the formula, A = lw, what could be the length and width of the rectangle?
length = (x − 8) units and width = (x − 9) units
length = (x + 9) units and width = (x + 8) units
length = (x − 6) units and width = (x − 12) units
length = (x + 12) units and width = (x + 6) units
Answer:
The results are the opposite sign of x1 and x2.
[tex]lenght \: = (x - 8) \: and \: width \: = (x - 9)[/tex]
Step-by-step explanation:
[tex] {x}^{2} - 17x + 72 = 0[/tex]
[tex]Δ = {(17)}^{2} - 4(1 \times 72)[/tex]
[tex]Δ = 289 - 288 = 1[/tex]
[tex]x1 \: and \: x2 = \frac{17± \sqrt{1}}{2} [/tex]
[tex]x1 = \frac{17 + 1}{2} = 9[/tex]
[tex]x2 = \frac{17 - 1}{2} = 8[/tex]

Calculate the kinetic energy of a boy of mass 65kg running with average speed of 20m/s (3mks)
This is equivalent to 13 kilojoules.
=======================================================
Work Shown:
m = 65 kg = mass
v = 20 m/s = velocity
KE = kinetic energy
KE = (1/2)*m*v^2
KE = (1/2)*65*(20)^2
KE = 13000 joules
This can be written as 13 kilojoules since "kilo" means "1 thousand"
The abbreviation of the unit "joules" is the letter J.

Before doing the question, let's recall the quadratic formula which is used to find the roots of a quadratic equation ;
For any quadratic equation of the form ax² + bx + c = 0 , it's roots are given by the quadratic formula as :
[tex]{\boxed{\bf{x=\dfrac{-b\pm \sqrt{D}}{2a}}}}[/tex]Where , D = b² - 4ac (Discriminant)
Now , simplifying the equation :
[tex]{:\implies \quad \sf -3\{(x)^{2}+2^{2}-2\times 2\times x\}+17=0\quad \qquad \{\because (a-b)^{2}=a^{2}+b^{2}-2ab\}}[/tex]
[tex]{:\implies \quad \sf -3(x^{2}+4-4x)+17=0}[/tex]
[tex]{:\implies \quad \sf -3x^{2}-12+12x+17=0}[/tex]
[tex]{:\implies \quad \sf -3x^{2}+12x+5=0}[/tex]
Dividing both sides by -1 will yield :
[tex]{:\implies \quad \sf 3x^{2}-12x-5=0}[/tex]
Now , it's in the form of the standard quadratic equation , where a = 3 , b = -12 , c = 5 , and D = (-12)² - 4 × 3 × -5 = 144+60 = 204
Now, By quadratic Formula ;
[tex]{:\implies \quad \sf x=\dfrac{-(-12)\pm \sqrt{204}}{2\times 3}}[/tex]
[tex]{:\implies \quad \sf x=\dfrac{12\pm 2\sqrt{51}}{2\times 3}}[/tex]
[tex]{:\implies \quad \sf x=\dfrac{\cancel{2}(6\pm \sqrt{51})}{\cancel{2}\times 3}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{x=\dfrac{6\pm \sqrt{51}}{3}}}}[/tex]

What is the area, in square units, of triangle RST?
Answer:
Step-by-step explanation:
The area of the larger rectangle is (4)(5)=20.
The area of the top left right triangle is (1/2)(2)(5)=5.
The area of the top right right triangle is (1/2)(2)(1)=1.
The area of the bottom right triangle is (1/2)(4)(4)=8.
So A = 20 - 5 - 1 - 8 = 15 - 9 = 6.

Please Help Me Complete My Assignment I'm On Question 9
Answer:
B
Step-by-step explanation:
Simply choose an x coordinate and plug it into the equations from the choices given.
i.e. where x=1
y=2(1)^2 - 4(1)
y= 2-4
y= -2
it can then be seen that where x=1 on the graph, y= -2 aligns perfectly
Answer:
B
Step-by-step explanation:
In y = 2x^2-4x, we put y = 0 to represent the intersection points on the x-axis of the graph. (Since y = 0 is always on the x-axis)
For 2x^2-4x = 0, using the quadratic formula, we get x = 0 and x = 2.
This matches the int. points on the graph.
Can someone please explain how to get the answer I've watched multiple videos on implicit derivatives and I still cant figure it out.
We're given the implicit equation
x² + 2x + y² - 4y = 12
where "implicit" means that one of the variables is considered a function of the other. In this case, the variable y = y(x) depends on the value of the variable x - in other words, the possible values of y are implied by the value of x. We then say that this equation defines y as an implicit function of x.
We're also given the implicit derivative,
dy/dx = (-2x - 2)/(2y - 4)
which tells us the rate of change y as a function of both x and y. The value of dy/dx corresponds to the slope of the tangent line to the curve defined by the implicit equation above at some point (x, y).
The tangent line is horizontal when its slope is zero. This happens when
(-2x - 2)/(2y - 4) = 0
If y ≠ 2, then we can eliminate the denominator and we're left with
-2x - 2 = 0
Solve for x :
-2x = 2
x = -1
This tells us that the points on the curve with x-coordinate -1 have a tangent line to the curve that is horizontal.
The tangent line is vertical when its slope is undefined/infinite, or equivalently when the denominator of dy/dx is zero:
2y - 4 = 0
Solve for y :
2y = 4
y = 2
So any point on the curve with y-coordinate 2 will have a tangent line there that is vertical.
By completing the square in the implicit equation, we can easily identify where these points are located.
x² + 2x + y² - 4y = 12
x² + 2x + 1 + y² - 4y + 4 = 17
(x + 1)² + (y - 2)² = 17
This equation defines a circle centered at (-1, 2) with radius √17. When x = -1, we have
(y - 2)² = 17 ⇒ y = 2 ± √17
and when y = 2, we have
(x + 1)² = 17 ⇒ x = -1 ± √17
See the attached plot to see the circle and the tangents at these points.
