Solution for (X-8)*(X-4)=32 equation:


Simplifying
(X + -8)(X + -4) = 32

Reorder the terms:
(-8 + X)(X + -4) = 32

Reorder the terms:
(-8 + X)(-4 + X) = 32

Multiply (-8 + X) * (-4 + X)
(-8(-4 + X) + X(-4 + X)) = 32
((-4 * -8 + X * -8) + X(-4 + X)) = 32
((32 + -8X) + X(-4 + X)) = 32
(32 + -8X + (-4 * X + X * X)) = 32
(32 + -8X + (-4X + X2)) = 32

Combine like terms: -8X + -4X = -12X
(32 + -12X + X2) = 32

Add '-32' to each side of the equation.
