Solution for (p+13)(p-4)= equation:


Simplifying
(p + 13)(p + -4) = 0

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

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

Multiply (13 + p) * (-4 + p)
(13(-4 + p) + p(-4 + p)) = 0
((-4 * 13 + p * 13) + p(-4 + p)) = 0
((-52 + 13p) + p(-4 + p)) = 0
(-52 + 13p + (-4 * p + p * p)) = 0
(-52 + 13p + (-4p + p2)) = 0
