Answer 1

4x^2−32x+28

Explanation:

Answer 2

The correct answer will be
`4x^(2) - 32x + 28`

Let's simplify step-by-step.

(x−7)(−9)+(x−7)(4x+5)

Distribute:

= (x)(−9)+(−7)(−9)+(x)(4x)+(x)(5)+(−7)(4x)+(−7)(5)

= −9x+63+4x2+5x+−28x+−35

Combine Like Terms:

= −9x+63+4x2+5x+−28x+−35

= (4x2)+(−9x+5x+−28x)+(63+−35)

= 4x2+−32x+28
