(x+2)(x-2)=35

Solution for (x+2)(x-2)=35 equation:

Simplifying
(x + 2)(x + -2) = 35

Reorder the terms:
(2 + x)(x + -2) = 35

Reorder the terms:
(2 + x)(-2 + x) = 35

Multiply (2 + x) * (-2 + x)
(2(-2 + x) + x(-2 + x)) = 35
((-2 * 2 + x * 2) + x(-2 + x)) = 35
((-4 + 2x) + x(-2 + x)) = 35
(-4 + 2x + (-2 * x + x * x)) = 35
(-4 + 2x + (-2x + x2)) = 35

Combine like terms: 2x + -2x = 0
(-4 + 0 + x2) = 35
(-4 + x2) = 35

Solving
-4 + x2 = 35
