Solution for (p-2)(p-9)=0 equation:


Simplifying
(p + -2)(p + -9) = 0

Reorder the terms:
(-2 + p)(p + -9) = 0

Reorder the terms:
(-2 + p)(-9 + p) = 0

Multiply (-2 + p) * (-9 + p)
(-2(-9 + p) + p(-9 + p)) = 0
((-9 * -2 + p * -2) + p(-9 + p)) = 0
((18 + -2p) + p(-9 + p)) = 0
(18 + -2p + (-9 * p + p * p)) = 0
(18 + -2p + (-9p + p2)) = 0
