Question

How do you simplify `3x (x -1) - 4 (x^2 - x)`?

Answer 1

x(1-x)

Explanation:

In order to simplify this equation , you need to expand it .

3x(x-1) - 4( x^2 - x) = 3x^2 - 3x - ( 4x^2 - 4x )

                         = 3x^2 - 3x - 4x^2 + 4x
                         =3x^2 - 4x^2 -3x + 4x

                         =-x^2 + x
                         rearrange = x- x^2
                         factorize   = x(1-x)

Hope this helps =)
