Solution for (v+21)(6v-1)=0 equation:


Simplifying
(v + 21)(6v + -1) = 0

Reorder the terms:
(21 + v)(6v + -1) = 0

Reorder the terms:
(21 + v)(-1 + 6v) = 0

Multiply (21 + v) * (-1 + 6v)
(21(-1 + 6v) + v(-1 + 6v)) = 0
((-1 * 21 + 6v * 21) + v(-1 + 6v)) = 0
((-21 + 126v) + v(-1 + 6v)) = 0
(-21 + 126v + (-1 * v + 6v * v)) = 0
(-21 + 126v + (-1v + 6v2)) = 0

Combine like terms: 126v + -1v = 125v
(-21 + 125v + 6v2) = 0

Solving
-21 + 125v + 6v2 = 0
