(p+8)(p-8)=0

Solution for (p+8)(p-8)=0 equation:

Simplifying
(p + 8)(p + -8) = 0

Reorder the terms:
(8 + p)(p + -8) = 0

Reorder the terms:
(8 + p)(-8 + p) = 0

Multiply (8 + p) * (-8 + p)
(8(-8 + p) + p(-8 + p)) = 0
((-8 * 8 + p * 8) + p(-8 + p)) = 0
((-64 + 8p) + p(-8 + p)) = 0
(-64 + 8p + (-8 * p + p * p)) = 0
(-64 + 8p + (-8p + p2)) = 0

Combine like terms: 8p + -8p = 0
(-64 + 0 + p2) = 0
(-64 + p2) = 0

Solving
-64 + p2 = 0

Solving for variable 'p'.

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

Add '64' to each side of the equation.
