Solution for v^2+12v+20=(v+10)(v) equation:


Simplifying
v2 + 12v + 20 = (v + 10)(v)

Reorder the terms:
20 + 12v + v2 = (v + 10)(v)

Reorder the terms:
20 + 12v + v2 = (10 + v)(v)

Reorder the terms for easier multiplication:
20 + 12v + v2 = v(10 + v)
20 + 12v + v2 = (10 * v + v * v)
20 + 12v + v2 = (10v + v2)

Add '-1v2' to each side of the equation.
20 + 12v + v2 + -1v2 = 10v + v2 + -1v2

Combine like terms: v2 + -1v2 = 0
20 + 12v + 0 = 10v + v2 + -1v2
20 + 12v = 10v + v2 + -1v2

Combine like terms: v2 + -1v2 = 0
20 + 12v = 10v + 0
20 + 12v = 10v

Solving
20 + 12v = 10v

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.

Add '-10v' to each side of the equation.
20 + 12v + -10v = 10v + -10v

Combine like terms: 12v + -10v = 2v
20 + 2v = 10v + -10v

Combine like terms: 10v + -10v = 0
20 + 2v = 0

Add '-20' to each side of the equation.
20 + -20 + 2v = 0 + -20

Combine like terms: 20 + -20 = 0
0 + 2v = 0 + -20
2v = 0 + -20
