Solution for (u-8)(u-4)= equation: 


Simplifying
(u + -8)(u + -4) = 0

Reorder the terms:
(-8 + u)(u + -4) = 0

Reorder the terms:
(-8 + u)(-4 + u) = 0

Multiply (-8 + u) * (-4 + u)
(-8(-4 + u) + u(-4 + u)) = 0
((-4 * -8 + u * -8) + u(-4 + u)) = 0
((32 + -8u) + u(-4 + u)) = 0
(32 + -8u + (-4 * u + u * u)) = 0
(32 + -8u + (-4u + u2)) = 0

Combine like terms: -8u + -4u = -12u
(32 + -12u + u2) = 0

Solving
32 + -12u + u2 = 0

Solving for variable 'u'.
