Question

What is the product?

2x(x – 4)

2x2 – 4
2x2 – 8
2x2 – 4x
2x2 – 8x

Answer 1

You are distributing here...so basically, you are taking the 2x and multiplying it by everything in the parenthesis...this will get rid of the parenthesis.
2x (x-4)
broken down, the problem is : 2x * x - 2x * 4 =
2x^2 - 8x

Answer 2

its 2x^2 - 8x because you have to multiply out the brackets so 2x multiplied by x is 2x^2 and 2x multiplied by 4 is 8x
