(p+3)(p-1)=0

Solution for (p+3)(p-1)=0 equation:

Simplifying
(p + 3)(p + -1) = 0

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

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

Multiply (3 + p) * (-1 + p)
(3(-1 + p) + p(-1 + p)) = 0
((-1 * 3 + p * 3) + p(-1 + p)) = 0
((-3 + 3p) + p(-1 + p)) = 0
(-3 + 3p + (-1 * p + p * p)) = 0
(-3 + 3p + (-1p + p2)) = 0

Combine like terms: 3p + -1p = 2p
(-3 + 2p + p2) = 0

Solving
-3 + 2p + p2 = 0

Solving for variable 'p'.

Factor a trinomial.
(-3 + -1p)(1 + -1p) = 0

Subproblem 1
Set the factor '(-3 + -1p)' equal to zero and attempt to solve:

1 + -1 + -1p = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1p = 0 + -1
-1p = 0 + -1

Combine like terms: 0 + -1 = -1
-1p = -1

Divide each side by '-1'.
p = 1

Simplifying
p = 1
Solution
p = {-3, 1}
