0=(P+6)(6-P)

Solution for 0=(P+6)(6-P) equation:

Simplifying
0 = (P + 6)(6 + -1P)

Reorder the terms:
0 = (6 + P)(6 + -1P)

Multiply (6 + P) * (6 + -1P)
0 = (6(6 + -1P) + P(6 + -1P))
0 = ((6 * 6 + -1P * 6) + P(6 + -1P))
0 = ((36 + -6P) + P(6 + -1P))
0 = (36 + -6P + (6 * P + -1P * P))
0 = (36 + -6P + (6P + -1P2))

Combine like terms: -6P + 6P = 0
0 = (36 + 0 + -1P2)
0 = (36 + -1P2)

Solving
0 = 36 + -1P2

Solving for variable 'P'.

Move all terms containing P to the left, all other terms to the right.

Add 'P2' to each side of the equation.
0 + P2 = 36 + -1P2 + P2
Remove the zero:
P2 = 36 + -1P2 + P2

Combine like terms: -1P2 + P2 = 0
P2 = 36 + 0
P2 = 36

Simplifying
P2 = 36

Take the square root of each side:
P = {-6, 6}
