Solution for (4v-1)(v+8)=0 equation:


Simplifying
(4v + -1)(v + 8) = 0

Reorder the terms:
(-1 + 4v)(v + 8) = 0

Reorder the terms:
(-1 + 4v)(8 + v) = 0

Multiply (-1 + 4v) * (8 + v)
(-1(8 + v) + 4v * (8 + v)) = 0
((8 * -1 + v * -1) + 4v * (8 + v)) = 0
((-8 + -1v) + 4v * (8 + v)) = 0
(-8 + -1v + (8 * 4v + v * 4v)) = 0
(-8 + -1v + (32v + 4v2)) = 0

Combine like terms: -1v + 32v = 31v
(-8 + 31v + 4v2) = 0

Solving
-8 + 31v + 4v2 = 0

Solving for variable 'v'.

Factor a trinomial.
