Answer:
2x^2 - 2
Step-by-step 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
Answer:2x-2
Step-by-step explanation:
(x-1)(2x+2)
=2[tex]x^{2}[/tex]+2x-2x-2
=2[tex]x^{2}[/tex]-2
