Solution for (5v-4)(1+v)=0 equation:


Simplifying
(5v + -4)(1 + v) = 0

Reorder the terms:
(-4 + 5v)(1 + v) = 0

Multiply (-4 + 5v) * (1 + v)
(-4(1 + v) + 5v * (1 + v)) = 0
((1 * -4 + v * -4) + 5v * (1 + v)) = 0
((-4 + -4v) + 5v * (1 + v)) = 0
(-4 + -4v + (1 * 5v + v * 5v)) = 0
(-4 + -4v + (5v + 5v2)) = 0

Combine like terms: -4v + 5v = 1v
(-4 + 1v + 5v2) = 0
