Solution for (p-1)(p-7)=0 equation:


Simplifying
(p + -1)(p + -7) = 0

Reorder the terms:
(-1 + p)(p + -7) = 0

Reorder the terms:
(-1 + p)(-7 + p) = 0

Multiply (-1 + p) * (-7 + p)
(-1(-7 + p) + p(-7 + p)) = 0
((-7 * -1 + p * -1) + p(-7 + p)) = 0
((7 + -1p) + p(-7 + p)) = 0
(7 + -1p + (-7 * p + p * p)) = 0
(7 + -1p + (-7p + p2)) = 0

Combine like terms: -1p + -7p = -8p
(7 + -8p + p2) = 0

Solving
7 + -8p + p2 = 0
