((-24 + -12t) + t(2 + t)) = t + -12
(-24 + -12t + (2 * t + t * t)) = t + -12
(-24 + -12t + (2t + t2)) = t + -12

Combine like terms: -12t + 2t = -10t
(-24 + -10t + t2) = t + -12

Reorder the terms:
-24 + -10t + t2 = -12 + t

Solving
-24 + -10t + t2 = -12 + t

Solving for variable 't'.

Reorder the terms:
-24 + 12 + -10t + -1t + t2 = -12 + t + 12 + -1t

Combine like terms: -24 + 12 = -12
-12 + -10t + -1t + t2 = -12 + t + 12 + -1t

Combine like terms: -10t + -1t = -11t
-12 + -11t + t2 = -12 + t + 12 + -1t

Reorder the terms:
-12 + -11t + t2 = -12 + 12 + t + -1t

Combine like terms: -12 + 12 = 0
-12 + -11t + t2 = 0 + t + -1t
-12 + -11t + t2 = t + -1t
