First you need to multiply through the first equation by the x on the outside of the ()

x^2 + 8x - 5x^2 -3x ( the 3x turned to a negative 3x because of the - outside of the ())

Now just combine like terms

-4x^2 + 5x

Now factor out a x, because they have an x in common

x(-4x + 5)

first you need to distribute

x(x + 8) - (5x^2 + 3x)

x^2 + 8x - 5x^2 - 3x now combine like terms

-4x^2 + 5x and you can pull an x out the say x(4x + 5) and that depends on your teacher and what they want.

x( x + 8) - (5x^2 + 3x)

x^2+8x -5x^2-3x = -4x^2 +5x =
x(5-4x)

x(x+8) - (5x^2 +3x)
x^2+8x-5x^2+3x
>>> 6x^2+11x <<<
