Simplifying
(4v + 2)(7 + v) = 0

Reorder the terms:
(2 + 4v)(7 + v) = 0

Multiply (2 + 4v) * (7 + v)
(2(7 + v) + 4v * (7 + v)) = 0
((7 * 2 + v * 2) + 4v * (7 + v)) = 0
((14 + 2v) + 4v * (7 + v)) = 0
(14 + 2v + (7 * 4v + v * 4v)) = 0
(14 + 2v + (28v + 4v2)) = 0

Combine like terms: 2v + 28v = 30v
(14 + 30v + 4v2) = 0
