Question

What is (2x – 2)(x – 1)

Answer 1

Hello!

First you multiply the 2x by the (x - 1)

2x * x = 2x^2
2x * -1 = -2x

Next you multiply the -2 by the (x - 1)

-2 * x = -2x
-2 * -1 = 2

Put the values together

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

Combine like terms

2x^2 - 4x + 2

The answer is 2x^2 - 4x + 2

Hope this helps!

Answer 2

Hello there!



Let's use foil.


First: 2x * x = 2x^2


Outside: 2x * -1 = -2x


Inside: -2 * x = -2x


Last: -2 * -1 = 2



Now, let's combine these.


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


Finally, we can simplify this


-2x - 2x = -4x


2x^2 - 4x + 2




I hope I helped!
