(x - 4)(x^2 + 3x + 2) =
x(x^2 + 3x + 2) - 4(x^2 + 3x + 2) =
x^3 + 3x^2 + 2x - 4x^2 - 12x - 8 =
x^3 -x^2 - 10x - 8

X/8+12=15 solve for x

Ilia_Sergeevich [38]

X/8 + 12 = 15
x/8 = 3 . ( start by subtracting 12 on both sides to get x on one side)
x = 24 ( now multiply by 8 on both sides to get x by itself and there is your answer )
