Question

Write the expression 5x(x + 9) − 7(x + 9) in complete factored form.

Answer 1

(x + 9)(x + 9)
(5x − 7)(x + 9)
(5x − 7)(x + 9)(x + 9)
(5x2 + 45x)(-7x − 63)

Answer 2

5x(x+9) (Distribute)

\[5x^{2}+45x\]

-7(x+9) Distribute

-7x-63

\[5x^{2}+45x-7x-63\]

Combine like terms and you'll get your answer.

Answer 3

Answer 4

The expression 5x(x + 9) + -7(x + 9) factors out to (-9 + -1x)(7 + -5x)
