Solution for (p+2)(p-4)= equation:


Simplifying
(p + 2)(p + -4) = 0

Reorder the terms:
(2 + p)(p + -4) = 0

Reorder the terms:
(2 + p)(-4 + p) = 0

Multiply (2 + p) * (-4 + p)
(2(-4 + p) + p(-4 + p)) = 0
((-4 * 2 + p * 2) + p(-4 + p)) = 0
((-8 + 2p) + p(-4 + p)) = 0
(-8 + 2p + (-4 * p + p * p)) = 0
(-8 + 2p + (-4p + p2)) = 0

Combine like terms: 2p + -4p = -2p
(-8 + -2p + p2) = 0

Solving
-8 + -2p + p2 = 0

Solving for variable 'p'.

Factor a trinomial.
