Solution for (2v+7)(5-v)=0 equation:


Simplifying
(2v + 7)(5 + -1v) = 0

Reorder the terms:
(7 + 2v)(5 + -1v) = 0

Multiply (7 + 2v) * (5 + -1v)
(7(5 + -1v) + 2v * (5 + -1v)) = 0
((5 * 7 + -1v * 7) + 2v * (5 + -1v)) = 0
((35 + -7v) + 2v * (5 + -1v)) = 0
(35 + -7v + (5 * 2v + -1v * 2v)) = 0
(35 + -7v + (10v + -2v2)) = 0

Combine like terms: -7v + 10v = 3v
(35 + 3v + -2v2) = 0
