Solution for (2p+3)(p-7)=0 equation:


Simplifying
(2p + 3)(p + -7) = 0

Reorder the terms:
(3 + 2p)(p + -7) = 0

Reorder the terms:
(3 + 2p)(-7 + p) = 0

Multiply (3 + 2p) * (-7 + p)
(3(-7 + p) + 2p * (-7 + p)) = 0
((-7 * 3 + p * 3) + 2p * (-7 + p)) = 0
((-21 + 3p) + 2p * (-7 + p)) = 0
(-21 + 3p + (-7 * 2p + p * 2p)) = 0
(-21 + 3p + (-14p + 2p2)) = 0

Combine like terms: 3p + -14p = -11p
(-21 + -11p + 2p2) = 0
