Solution for (V+9)(v-9)= equation:


Simplifying
(V + 9)(v + -9) = 0

Reorder the terms:
(9 + V)(v + -9) = 0

Reorder the terms:
(9 + V)(-9 + v) = 0

Multiply (9 + V) * (-9 + v)
(9(-9 + v) + V(-9 + v)) = 0
((-9 * 9 + v * 9) + V(-9 + v)) = 0
((-81 + 9v) + V(-9 + v)) = 0
(-81 + 9v + (-9 * V + v * V)) = 0
(-81 + 9v + (-9V + vV)) = 0

Reorder the terms:
(-81 + -9V + 9v + vV) = 0
(-81 + -9V + 9v + vV) = 0

Solving
-81 + -9V + 9v + vV = 0

Solving for variable 'V'.

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

Add '81' to each side of the equation.
-81 + -9V + 9v + 81 + vV = 0 + 81

Reorder the terms:
-81 + 81 + -9V + 9v + vV = 0 + 81

Combine like terms: -81 + 81 = 0
0 + -9V + 9v + vV = 0 + 81
-9V + 9v + vV = 0 + 81
