Question

What is the factored form of the polynomial?

x2 − 12x + 27?

a.(x + 4)(x + 3)
b.(x − 4)(x + 3)
c.(x + 9)(x + 3)
d.(x − 9)(x − 3)

Answer 1

D. (x − 9)(x − 3)

Explanation:

Answer 2

d.(x - 9) (x - 3)

Explanation:

x² - 12x + 27 = 0

x² - 9x - 3x + 27 = 0

x(x - 9) - 3(x - 9) = 0

(x - 9) (x - 3) = 0
