y=(t-2)(t+1)(t+1)

Solution for y=(t-2)(t+1)(t+1) equation:

Simplifying
y = (t + -2)(t + 1)(t + 1)

Reorder the terms:
y = (-2 + t)(t + 1)(t + 1)

Reorder the terms:
y = (-2 + t)(1 + t)(t + 1)

Reorder the terms:
y = (-2 + t)(1 + t)(1 + t)

Multiply (-2 + t) * (1 + t)
y = (-2(1 + t) + t(1 + t))(1 + t)
y = ((1 * -2 + t * -2) + t(1 + t))(1 + t)
y = ((-2 + -2t) + t(1 + t))(1 + t)
y = (-2 + -2t + (1 * t + t * t))(1 + t)
y = (-2 + -2t + (1t + t2))(1 + t)

Combine like terms: -2t + 1t = -1t
y = (-2 + -1t + t2)(1 + t)

Multiply (-2 + -1t + t2) * (1 + t)
y = (-2(1 + t) + -1t * (1 + t) + t2(1 + t))
y = ((1 * -2 + t * -2) + -1t * (1 + t) + t2(1 + t))
y = ((-2 + -2t) + -1t * (1 + t) + t2(1 + t))
y = (-2 + -2t + (1 * -1t + t * -1t) + t2(1 + t))
y = (-2 + -2t + (-1t + -1t2) + t2(1 + t))
y = (-2 + -2t + -1t + -1t2 + (1 * t2 + t * t2))
y = (-2 + -2t + -1t + -1t2 + (1t2 + t3))

Combine like terms: -2t + -1t = -3t
y = (-2 + -3t + -1t2 + 1t2 + t3)

Combine like terms: -1t2 + 1t2 = 0
y = (-2 + -3t + 0 + t3)
y = (-2 + -3t + t3)

Solving
y = -2 + -3t + t3

Solving for variable 'y'.

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

Simplifying
y = -2 + -3t + t3
