Solution for 126=(h+4)(h+3)(h) equation: 


Simplifying
126 = (h + 4)(h + 3)(h)

Reorder the terms:
126 = (4 + h)(h + 3)(h)

Reorder the terms:
126 = (4 + h)(3 + h)(h)

Reorder the terms for easier multiplication:
126 = h(4 + h)(3 + h)

Multiply (4 + h) * (3 + h)
126 = h(4(3 + h) + h(3 + h))
126 = h((3 * 4 + h * 4) + h(3 + h))
126 = h((12 + 4h) + h(3 + h))
126 = h(12 + 4h + (3 * h + h * h))
126 = h(12 + 4h + (3h + h2))

Combine like terms: 4h + 3h = 7h
126 = h(12 + 7h + h2)
126 = (12 * h + 7h * h + h2 * h)
126 = (12h + 7h2 + h3)

Solving
126 = 12h + 7h2 + h3

Solving for variable 'h'.

Reorder the terms:
126 + -12h + -7h2 + -1h3 = 12h + -12h + 7h2 + -7h2 + h3 + -1h3

Combine like terms: 12h + -12h = 0
126 + -12h + -7h2 + -1h3 = 0 + 7h2 + -7h2 + h3 + -1h3
126 + -12h + -7h2 + -1h3 = 7h2 + -7h2 + h3 + -1h3

Combine like terms: 7h2 + -7h2 = 0
126 + -12h + -7h2 + -1h3 = 0 + h3 + -1h3
126 + -12h + -7h2 + -1h3 = h3 + -1h3

Combine like terms: h3 + -1h3 = 0
126 + -12h + -7h2 + -1h3 = 0
