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


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

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

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

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

Combine like terms: -7v + -5v = -12v
(35 + -12v + v2) = 0

Solving
35 + -12v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.
