Solution for (v+15)(v-18)=0 equation: 


Simplifying
(v + 15)(v + -18) = 0

Reorder the terms:
(15 + v)(v + -18) = 0

Reorder the terms:
(15 + v)(-18 + v) = 0

Multiply (15 + v) * (-18 + v)
(15(-18 + v) + v(-18 + v)) = 0
((-18 * 15 + v * 15) + v(-18 + v)) = 0
((-270 + 15v) + v(-18 + v)) = 0
(-270 + 15v + (-18 * v + v * v)) = 0
(-270 + 15v + (-18v + v2)) = 0

Combine like terms: 15v + -18v = -3v
(-270 + -3v + v2) = 0

Solving
-270 + -3v + v2 = 0
