v^2-g^2=0

Solution for v^2-g^2=0 equation:

Simplifying
v2 + -1g2 = 0

Reorder the terms:
-1g2 + v2 = 0

Solving
-1g2 + v2 = 0

Solving for variable 'g'.

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

Add '-1v2' to each side of the equation.
-1g2 + v2 + -1v2 = 0 + -1v2

Combine like terms: v2 + -1v2 = 0
-1g2 + 0 = 0 + -1v2
-1g2 = 0 + -1v2
Remove the zero:
-1g2 = -1v2

Divide each side by '-1'.
g2 = v2

Simplifying
g2 = v2

Take the square root of each side:
g = {-1v, v}
