(2t-3)(t+5)=0

Solution for (2t-3)(t+5)=0 equation:

Simplifying
(2t + -3)(t + 5) = 0

Reorder the terms:
(-3 + 2t)(t + 5) = 0

Reorder the terms:
(-3 + 2t)(5 + t) = 0

Multiply (-3 + 2t) * (5 + t)
(-3(5 + t) + 2t * (5 + t)) = 0
((5 * -3 + t * -3) + 2t * (5 + t)) = 0
((-15 + -3t) + 2t * (5 + t)) = 0
(-15 + -3t + (5 * 2t + t * 2t)) = 0
(-15 + -3t + (10t + 2t2)) = 0

Combine like terms: -3t + 10t = 7t
(-15 + 7t + 2t2) = 0

Solving
-15 + 7t + 2t2 = 0

Solving for variable 't'.
