Question

Does anyone know how to do this

Answer 1

7 (x-1)(x+5)

Explanation:

Find

GCF = 7

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

7 (7x^2/7 + 28x/7 - 35/7)

Simplify each term in parentheses.

7 (x^2 +4x-5)

Simplify.

Answer 2

`7 {x}^(2) + 28x - 35 = 0`

`7 {x}^(2) + 35x - 7x - 35 = 0`

`7x(x + 5) - 7(x + 5) = 0`

`(x + 5)(7x - 7) = 0`

`(x + 5)(x - 1) = 0`
