Solution for (v+3)(v+7)=0 equation:


Simplifying
(v + 3)(v + 7) = 0

Reorder the terms:
(3 + v)(v + 7) = 0

Reorder the terms:
(3 + v)(7 + v) = 0

Multiply (3 + v) * (7 + v)
(3(7 + v) + v(7 + v)) = 0
((7 * 3 + v * 3) + v(7 + v)) = 0
((21 + 3v) + v(7 + v)) = 0
(21 + 3v + (7 * v + v * v)) = 0
(21 + 3v + (7v + v2)) = 0

Combine like terms: 3v + 7v = 10v
(21 + 10v + v2) = 0

Solving
21 + 10v + v2 = 0
