(x+8)(x-8)=y

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

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

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

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

Multiply (8 + x) * (-8 + x)
(8(-8 + x) + x(-8 + x)) = y
((-8 * 8 + x * 8) + x(-8 + x)) = y
((-64 + 8x) + x(-8 + x)) = y
(-64 + 8x + (-8 * x + x * x)) = y
(-64 + 8x + (-8x + x2)) = y

Combine like terms: 8x + -8x = 0
(-64 + 0 + x2) = y
(-64 + x2) = y

Solving
-64 + x2 = y

Solving for variable 'x'.

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

Add '64' to each side of the equation.
-64 + 64 + x2 = 64 + y

Combine like terms: -64 + 64 = 0
0 + x2 = 64 + y
x2 = 64 + y

Simplifying
x2 = 64 + y

Reorder the terms:
-64 + x2 + -1y = 64 + y + -64 + -1y

Reorder the terms:
-64 + x2 + -1y = 64 + -64 + y + -1y

Combine like terms: 64 + -64 = 0
-64 + x2 + -1y = 0 + y + -1y
-64 + x2 + -1y = y + -1y

Combine like terms: y + -1y = 0
-64 + x2 + -1y = 0
