Answer to Question 2:</h3>
The answer to question 2 is 8x - 37
Step-by-step explanation:
Firstly, do the distributive property to simplify the terms within the bracket.
4(2x + 10) -3 ---> 8x + 40 - 3
Next, combine like terms
8x + 40 - 3 ---> <u>8x - 37</u>
<em>That's All!</em>

Answer to Question 3:</h3>
The answer to question 3 is 6(4c−3)
Step-by-step explanation:
Firstly, find the largest shared factor of 24 and 18, in the equation 24c−18
24: 1,2,3,4,6,8,12,24
18: 1,2,3,6,9,18
The largest between both of them is 6.
Next Step, divide both terms in the equation by 6.
24c−18 ---> 4c-3
Lastly, add brackets add a 6 on the outside of them.
4c-3 ---> 6(4c-3)

Answer:
y = 2x² - 5x + 7
Step-by-step explanation:
General form of a quadratic is:
y = Ax² + Bx + C
Using the given points, construct equations and solve for A,B and C.
When x = 0, y = 7
7 = A(0)² + B(0) + C
C = 7
y = Ax² + Bx + 7
When x = -1, y = 14
14 = A(-1)² + B(-1) + 7
A - B = 7
A = 7 + B
When x = 1, y = 4
4 = A(1)² + B(1) + 7
A + B = -3
(7 + B) + B = -3
2B = -10
B = -5
A = 7 + (-5)
A = 2
y = 2x² - 5x + 7
