h=-5(t-5)(t+1)

Solution for h=-5(t-5)(t+1) equation:

Simplifying
h = -5(t + -5)(t + 1)

Reorder the terms:
h = -5(-5 + t)(t + 1)

Reorder the terms:
h = -5(-5 + t)(1 + t)

Multiply (-5 + t) * (1 + t)
h = -5(-5(1 + t) + t(1 + t))
h = -5((1 * -5 + t * -5) + t(1 + t))
h = -5((-5 + -5t) + t(1 + t))
h = -5(-5 + -5t + (1 * t + t * t))
h = -5(-5 + -5t + (1t + t2))

Combine like terms: -5t + 1t = -4t
h = -5(-5 + -4t + t2)
h = (-5 * -5 + -4t * -5 + t2 * -5)
h = (25 + 20t + -5t2)

Solving
h = 25 + 20t + -5t2

Solving for variable 'h'.

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

Simplifying
