Factorize the following quadratic expressions a) x^2 − 11x – 42

b) x^2 − 12x − 45

c) x^2 − 7x – 30

d) x^2 − 5x − 24

e) 3x^2 + 10x + 8

a) (x + 3)(x - 14)

b) (x + 3)(x - 15)

c) (x + 3)(x - 10)

d) (x + 3)(x - 8)

e) (3x + 4)(x + 2)

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
