(480-x)(480+x)=

Solution for (480-x)(480+x)= equation:

Simplifying
(480 + -1x)(480 + x) = 0

Multiply (480 + -1x) * (480 + x)
(480(480 + x) + -1x * (480 + x)) = 0
((480 * 480 + x * 480) + -1x * (480 + x)) = 0
((230400 + 480x) + -1x * (480 + x)) = 0
(230400 + 480x + (480 * -1x + x * -1x)) = 0
(230400 + 480x + (-480x + -1x2)) = 0

Combine like terms: 480x + -480x = 0
(230400 + 0 + -1x2) = 0
(230400 + -1x2) = 0

Solving
230400 + -1x2 = 0

Solving for variable 'x'.

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

Add '-230400' to each side of the equation.
230400 + -230400 + -1x2 = 0 + -230400

Combine like terms: 230400 + -230400 = 0
0 + -1x2 = 0 + -230400
-1x2 = 0 + -230400

Combine like terms: 0 + -230400 = -230400
-1x2 = -230400

Divide each side by '-1'.
x2 = 230400

Simplifying
x2 = 230400

Take the square root of each side:
x = {-480, 480}
