Question

(x-1)(2x+2)
Can you please show all of your work.

Answer 1

Answer:2x-2

Explanation:

(x-1)(2x+2)

=2
`x^(2)`+2x-2x-2

=2
`x^(2)`-2

Answer 2

2x^2 - 2

Explanation:

FOIL:

First outer inner last.

So we take (x-1) and (2x+2) and multiply the two first terms together.

2x^2

Next, we do the two outer terms.

2x^2 + 2x

Inner is next.

2x^2 + 2x - 2x

Then the last two terms in the equation.

2x^2 + 2x - 2x - 2

Then simplify:

2x^2 - 2
