Solution for (7v-5)(v-2)=0 equation:


Simplifying
(7v + -5)(v + -2) = 0

Reorder the terms:
(-5 + 7v)(v + -2) = 0

Reorder the terms:
(-5 + 7v)(-2 + v) = 0

Multiply (-5 + 7v) * (-2 + v)
(-5(-2 + v) + 7v * (-2 + v)) = 0
((-2 * -5 + v * -5) + 7v * (-2 + v)) = 0
((10 + -5v) + 7v * (-2 + v)) = 0
(10 + -5v + (-2 * 7v + v * 7v)) = 0
(10 + -5v + (-14v + 7v2)) = 0

Combine like terms: -5v + -14v = -19v
(10 + -19v + 7v2) = 0

Solving
10 + -19v + 7v2 = 0
