(3y-3g)(3y+3g)=

Solution for (3y-3g)(3y+3g)= equation:

Simplifying
(3y + -3g)(3y + 3g) = 0

Reorder the terms:
(-3g + 3y)(3y + 3g) = 0

Reorder the terms:
(-3g + 3y)(3g + 3y) = 0

Multiply (-3g + 3y) * (3g + 3y)
(-3g * (3g + 3y) + 3y * (3g + 3y)) = 0
((3g * -3g + 3y * -3g) + 3y * (3g + 3y)) = 0

Reorder the terms:
((-9gy + -9g2) + 3y * (3g + 3y)) = 0
((-9gy + -9g2) + 3y * (3g + 3y)) = 0
(-9gy + -9g2 + (3g * 3y + 3y * 3y)) = 0
(-9gy + -9g2 + (9gy + 9y2)) = 0

Reorder the terms:
(-9gy + 9gy + -9g2 + 9y2) = 0

Combine like terms: -9gy + 9gy = 0
(0 + -9g2 + 9y2) = 0
(-9g2 + 9y2) = 0

Solving
-9g2 + 9y2 = 0

Solving for variable 'g'.

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

Add '-9y2' to each side of the equation.
-9g2 + 9y2 + -9y2 = 0 + -9y2

Combine like terms: 9y2 + -9y2 = 0
-9g2 + 0 = 0 + -9y2
-9g2 = 0 + -9y2
Remove the zero:
-9g2 = -9y2

Divide each side by '-9'.
g2 = y2

Simplifying
g2 = y2

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