Solution for (p+1)(p-8)=0 equation:


Simplifying
(p + 1)(p + -8) = 0

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

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

Multiply (1 + p) * (-8 + p)
(1(-8 + p) + p(-8 + p)) = 0
((-8 * 1 + p * 1) + p(-8 + p)) = 0
((-8 + 1p) + p(-8 + p)) = 0
(-8 + 1p + (-8 * p + p * p)) = 0
(-8 + 1p + (-8p + p2)) = 0

Combine like terms: 1p + -8p = -7p
(-8 + -7p + p2) = 0

Solving
-8 + -7p + p2 = 0
