Solution for (h-2)(h-4)=0 equation:


Simplifying
(h + -2)(h + -4) = 0

Reorder the terms:
(-2 + h)(h + -4) = 0

Reorder the terms:
(-2 + h)(-4 + h) = 0

Multiply (-2 + h) * (-4 + h)
(-2(-4 + h) + h(-4 + h)) = 0
((-4 * -2 + h * -2) + h(-4 + h)) = 0
((8 + -2h) + h(-4 + h)) = 0
(8 + -2h + (-4 * h + h * h)) = 0
(8 + -2h + (-4h + h2)) = 0

Combine like terms: -2h + -4h = -6h
(8 + -6h + h2) = 0

Solving
8 + -6h + h2 = 0

Solving for variable 'h'.
