Solution for (4v+7)(2-v)=0 equation:


Simplifying
(4v + 7)(2 + -1v) = 0

Reorder the terms:
(7 + 4v)(2 + -1v) = 0

Multiply (7 + 4v) * (2 + -1v)
(7(2 + -1v) + 4v * (2 + -1v)) = 0
((2 * 7 + -1v * 7) + 4v * (2 + -1v)) = 0
((14 + -7v) + 4v * (2 + -1v)) = 0
(14 + -7v + (2 * 4v + -1v * 4v)) = 0
(14 + -7v + (8v + -4v2)) = 0

Combine like terms: -7v + 8v = 1v
(14 + 1v + -4v2) = 0

Solving
14 + 1v + -4v2 = 0
