What is the completely factored form of this expression?

y2 - 12y + 32

A.

(y + 4) (y + 8)

B.

(y - 4) (y - 8)

C.

(y + 18) (y + 2)

D.

(y - 18) (y - 2)

B

Step-by-step explanation:

Given

y² - 12y + 32

Consider the factors of the constant term ( + 32) which sum to give the coefficient of the x - term ( - 12)

The factors are - 4 and - 8, since

- 4 * - 8 = + 32 and - 4 - 8 = - 12, thus

y² - 12y + 32 = (x - 4) (x - 8) → B

B is your answer
