(p+5)(p-1)=0

Solution for (p+5)(p-1)=0 equation:

Simplifying
(p + 5)(p + -1) = 0

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

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

Multiply (5 + p) * (-1 + p)
(5(-1 + p) + p(-1 + p)) = 0
((-1 * 5 + p * 5) + p(-1 + p)) = 0
((-5 + 5p) + p(-1 + p)) = 0
(-5 + 5p + (-1 * p + p * p)) = 0
(-5 + 5p + (-1p + p2)) = 0

Combine like terms: 5p + -1p = 4p
(-5 + 4p + p2) = 0

Solving
-5 + 4p + p2 = 0

Solving for variable 'p'.
