Solution for (t-4)(t+3)= equation:


Simplifying
(t + -4)(t + 3) = 0

Reorder the terms:
(-4 + t)(t + 3) = 0

Reorder the terms:
(-4 + t)(3 + t) = 0

Multiply (-4 + t) * (3 + t)
(-4(3 + t) + t(3 + t)) = 0
((3 * -4 + t * -4) + t(3 + t)) = 0
((-12 + -4t) + t(3 + t)) = 0
(-12 + -4t + (3 * t + t * t)) = 0
(-12 + -4t + (3t + t2)) = 0

Combine like terms: -4t + 3t = -1t
(-12 + -1t + t2) = 0

Solving
-12 + -1t + t2 = 0
