Solution for (v-3)(v-3)=2v^2-9v-9 equation:


Simplifying
(v + -3)(v + -3) = 2v2 + -9v + -9

Reorder the terms:
(-3 + v)(v + -3) = 2v2 + -9v + -9

Reorder the terms:
(-3 + v)(-3 + v) = 2v2 + -9v + -9

Multiply (-3 + v) * (-3 + v)
(-3(-3 + v) + v(-3 + v)) = 2v2 + -9v + -9
((-3 * -3 + v * -3) + v(-3 + v)) = 2v2 + -9v + -9
((9 + -3v) + v(-3 + v)) = 2v2 + -9v + -9
(9 + -3v + (-3 * v + v * v)) = 2v2 + -9v + -9
(9 + -3v + (-3v + v2)) = 2v2 + -9v + -9

Combine like terms: -3v + -3v = -6v
(9 + -6v + v2) = 2v2 + -9v + -9

Reorder the terms:
9 + -6v + v2 = -9 + -9v + 2v2

Solving
9 + -6v + v2 = -9 + -9v + 2v2

Solving for variable 'v'.

Reorder the terms:
9 + 9 + -6v + 9v + v2 + -2v2 = -9 + -9v + 2v2 + 9 + 9v + -2v2

Combine like terms: 9 + 9 = 18
18 + -6v + 9v + v2 + -2v2 = -9 + -9v + 2v2 + 9 + 9v + -2v2

Combine like terms: -6v + 9v = 3v
18 + 3v + v2 + -2v2 = -9 + -9v + 2v2 + 9 + 9v + -2v2

Combine like terms: v2 + -2v2 = -1v2
18 + 3v + -1v2 = -9 + -9v + 2v2 + 9 + 9v + -2v2

Reorder the terms:
18 + 3v + -1v2 = -9 + 9 + -9v + 9v + 2v2 + -2v2

Combine like terms: -9 + 9 = 0
18 + 3v + -1v2 = 0 + -9v + 9v + 2v2 + -2v2
18 + 3v + -1v2 = -9v + 9v + 2v2 + -2v2

Combine like terms: -9v + 9v = 0
18 + 3v + -1v2 = 0 + 2v2 + -2v2
18 + 3v + -1v2 = 2v2 + -2v2

Combine like terms: 2v2 + -2v2 = 0
18 + 3v + -1v2 = 0
