Solution for (h-3)(4+h)=60 equation:


Simplifying
(h + -3)(4 + h) = 60

Reorder the terms:
(-3 + h)(4 + h) = 60

Multiply (-3 + h) * (4 + h)
(-3(4 + h) + h(4 + h)) = 60
((4 * -3 + h * -3) + h(4 + h)) = 60
((-12 + -3h) + h(4 + h)) = 60
(-12 + -3h + (4 * h + h * h)) = 60
(-12 + -3h + (4h + h2)) = 60

Combine like terms: -3h + 4h = 1h
(-12 + 1h + h2) = 60

Solving
-12 + 1h + h2 = 60

Solving for variable 'h'.

Reorder the terms:
-12 + -60 + 1h + h2 = 60 + -60

Combine like terms: -12 + -60 = -72
