(8-x)(8+x)=

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

Simplifying
(8 + -1x)(8 + x) = 0

Multiply (8 + -1x) * (8 + x)
(8(8 + x) + -1x * (8 + x)) = 0
((8 * 8 + x * 8) + -1x * (8 + x)) = 0
((64 + 8x) + -1x * (8 + x)) = 0
(64 + 8x + (8 * -1x + x * -1x)) = 0
(64 + 8x + (-8x + -1x2)) = 0

Combine like terms: 8x + -8x = 0
(64 + 0 + -1x2) = 0
(64 + -1x2) = 0

Solving
64 + -1x2 = 0

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 + -1x2 = 0 + -64

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

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

Divide each side by '-1'.
x2 = 64

Simplifying
x2 = 64

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