h=-16(t-9)(t+9)

Solution for h=-16(t-9)(t+9) equation:

Simplifying
h = -16(t + -9)(t + 9)

Reorder the terms:
h = -16(-9 + t)(t + 9)

Reorder the terms:
h = -16(-9 + t)(9 + t)

Multiply (-9 + t) * (9 + t)
h = -16(-9(9 + t) + t(9 + t))
h = -16((9 * -9 + t * -9) + t(9 + t))
h = -16((-81 + -9t) + t(9 + t))
h = -16(-81 + -9t + (9 * t + t * t))
h = -16(-81 + -9t + (9t + t2))

Combine like terms: -9t + 9t = 0
h = -16(-81 + 0 + t2)
h = -16(-81 + t2)
h = (-81 * -16 + t2 * -16)
h = (1296 + -16t2)

Solving
h = 1296 + -16t2

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.
