Solution for (v+7)(v-18)=0 equation:


Simplifying
(v + 7)(v + -18) = 0

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

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

Multiply (7 + v) * (-18 + v)
(7(-18 + v) + v(-18 + v)) = 0
((-18 * 7 + v * 7) + v(-18 + v)) = 0
((-126 + 7v) + v(-18 + v)) = 0
(-126 + 7v + (-18 * v + v * v)) = 0
(-126 + 7v + (-18v + v2)) = 0

Combine like terms: 7v + -18v = -11v
(-126 + -11v + v2) = 0

Solving
-126 + -11v + v2 = 0

Solving for variable 'v'.
