Solution for (5v-6)(7+v)=0 equation:


Simplifying
(5v + -6)(7 + v) = 0

Reorder the terms:
(-6 + 5v)(7 + v) = 0

Multiply (-6 + 5v) * (7 + v)
(-6(7 + v) + 5v * (7 + v)) = 0
((7 * -6 + v * -6) + 5v * (7 + v)) = 0
((-42 + -6v) + 5v * (7 + v)) = 0
(-42 + -6v + (7 * 5v + v * 5v)) = 0
(-42 + -6v + (35v + 5v2)) = 0

Combine like terms: -6v + 35v = 29v
(-42 + 29v + 5v2) = 0
