Question

Help! please and thank you!!

Answer 1

`y= (x-4)(x+2)`

Explanation:

To factor polynomials you have to use FOIL. Which stands for First, Outer, Inner, and Last. This means that you have to multiply the first numbers of each part by each other, the outer two between both parts, the inner two between both parts, and the last two of each part, respectively. Then, you would simplify. If you go and do this for each answer choice, the last one would be the only correct one.

Answer 2

y = (x - 4)(x + 2)

Explanation:

Quadratic Formula:

• ax² + bx + c = 0

Substitute 1 for a, -2 for b, and -8 - y for c in the quadratic formula.
