Solution for 12=(h)(h-1)(h+4) equation: 


Simplifying
12 = (h)(h + -1)(h + 4)

Reorder the terms:
12 = h(-1 + h)(h + 4)

Reorder the terms:
12 = h(-1 + h)(4 + h)

Multiply (-1 + h) * (4 + h)
12 = h(-1(4 + h) + h(4 + h))
12 = h((4 * -1 + h * -1) + h(4 + h))
12 = h((-4 + -1h) + h(4 + h))
12 = h(-4 + -1h + (4 * h + h * h))
12 = h(-4 + -1h + (4h + h2))

Combine like terms: -1h + 4h = 3h
12 = h(-4 + 3h + h2)
12 = (-4 * h + 3h * h + h2 * h)
12 = (-4h + 3h2 + h3)

Solving
12 = -4h + 3h2 + h3

Solving for variable 'h'.

Reorder the terms:
12 + 4h + -3h2 + -1h3 = -4h + 4h + 3h2 + -3h2 + h3 + -1h3

Combine like terms: -4h + 4h = 0
12 + 4h + -3h2 + -1h3 = 0 + 3h2 + -3h2 + h3 + -1h3
12 + 4h + -3h2 + -1h3 = 3h2 + -3h2 + h3 + -1h3

Combine like terms: 3h2 + -3h2 = 0
12 + 4h + -3h2 + -1h3 = 0 + h3 + -1h3
12 + 4h + -3h2 + -1h3 = h3 + -1h3

Combine like terms: h3 + -1h3 = 0
12 + 4h + -3h2 + -1h3 = 0
