(y-8)*(y+8)=

Solution for (y-8)*(y+8)= equation:

Simplifying
(y + -8)(y + 8) = 0

Reorder the terms:
(-8 + y)(y + 8) = 0

Reorder the terms:
(-8 + y)(8 + y) = 0

Multiply (-8 + y) * (8 + y)
(-8(8 + y) + y(8 + y)) = 0
((8 * -8 + y * -8) + y(8 + y)) = 0
((-64 + -8y) + y(8 + y)) = 0
(-64 + -8y + (8 * y + y * y)) = 0
(-64 + -8y + (8y + y2)) = 0

Combine like terms: -8y + 8y = 0
(-64 + 0 + y2) = 0
(-64 + y2) = 0

Solving
-64 + y2 = 0

Solving for variable 'y'.

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

Add '64' to each side of the equation.
-64 + 64 + y2 = 0 + 64

Combine like terms: -64 + 64 = 0
0 + y2 = 0 + 64
y2 = 0 + 64

Combine like terms: 0 + 64 = 64
y2 = 64

Simplifying
y2 = 64

Take the square root of each side:
y = {-8, 8}
