(2*x-8)*(x+3)=0

Solution for (2*x-8)*(x+3)=0 equation:

Simplifying
(2x + -8)(x + 3) = 0

Reorder the terms:
(-8 + 2x)(x + 3) = 0

Reorder the terms:
(-8 + 2x)(3 + x) = 0

Multiply (-8 + 2x) * (3 + x)
(-8(3 + x) + 2x * (3 + x)) = 0
((3 * -8 + x * -8) + 2x * (3 + x)) = 0
((-24 + -8x) + 2x * (3 + x)) = 0
(-24 + -8x + (3 * 2x + x * 2x)) = 0
(-24 + -8x + (6x + 2x2)) = 0

Combine like terms: -8x + 6x = -2x
(-24 + -2x + 2x2) = 0

Solving
-24 + -2x + 2x2 = 0
