(x-2)(x+2)=60

Solution for (x-2)(x+2)=60 equation:

Simplifying
(x + -2)(x + 2) = 60

Reorder the terms:
(-2 + x)(x + 2) = 60

Reorder the terms:
(-2 + x)(2 + x) = 60

Multiply (-2 + x) * (2 + x)
(-2(2 + x) + x(2 + x)) = 60
((2 * -2 + x * -2) + x(2 + x)) = 60
((-4 + -2x) + x(2 + x)) = 60
(-4 + -2x + (2 * x + x * x)) = 60
(-4 + -2x + (2x + x2)) = 60

Combine like terms: -2x + 2x = 0
(-4 + 0 + x2) = 60
(-4 + x2) = 60

Solving
-4 + x2 = 60
