(p+2)(p-2)=

Solution for (p+2)(p-2)= equation:

Simplifying
(p + 2)(p + -2) = 0

Reorder the terms:
(2 + p)(p + -2) = 0

Reorder the terms:
(2 + p)(-2 + p) = 0

Multiply (2 + p) * (-2 + p)
(2(-2 + p) + p(-2 + p)) = 0
((-2 * 2 + p * 2) + p(-2 + p)) = 0
((-4 + 2p) + p(-2 + p)) = 0
(-4 + 2p + (-2 * p + p * p)) = 0
(-4 + 2p + (-2p + p2)) = 0

Combine like terms: 2p + -2p = 0
(-4 + 0 + p2) = 0
(-4 + p2) = 0

Solving
-4 + p2 = 0

Solving for variable 'p'.

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

Add '4' to each side of the equation.
-4 + 4 + p2 = 0 + 4

Combine like terms: -4 + 4 = 0
0 + p2 = 0 + 4
p2 = 0 + 4

Combine like terms: 0 + 4 = 4
p2 = 4

Simplifying
p2 = 4

Take the square root of each side:
p = {-2, 2}
