(y+6)(y-6)=

Solution for (y+6)(y-6)= equation:

Simplifying
(y + 6)(y + -6) = 0

Reorder the terms:
(6 + y)(y + -6) = 0

Reorder the terms:
(6 + y)(-6 + y) = 0

Multiply (6 + y) * (-6 + y)
(6(-6 + y) + y(-6 + y)) = 0
((-6 * 6 + y * 6) + y(-6 + y)) = 0
((-36 + 6y) + y(-6 + y)) = 0
(-36 + 6y + (-6 * y + y * y)) = 0
(-36 + 6y + (-6y + y2)) = 0

Combine like terms: 6y + -6y = 0
(-36 + 0 + y2) = 0
(-36 + y2) = 0

Solving
-36 + y2 = 0

Solving for variable 'y'.

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

Add '36' to each side of the equation.
-36 + 36 + y2 = 0 + 36

Combine like terms: -36 + 36 = 0
0 + y2 = 0 + 36
y2 = 0 + 36

Combine like terms: 0 + 36 = 36
y2 = 36

Simplifying
y2 = 36

Take the square root of each side:
y = {-6, 6}
