We will use the FOIL method to solve this.

(7x-7)(x+1)

Multiply 7x by x. Then, multiply 7x by 1. Then, multiply -7 by x. Then, Multiply -7 by 1.

[tex]7x^{2} + 7x - 7x -7[/tex]

Now, we need to simplify by combining like terms.

[tex]7x^{2} -7[/tex]

If you look, -7x and 7x are gone. This is because they cancel each other out.

I hope this helped and maybe consider giving me brainliest :)
