(x+9)(x-6)=

Solution for (x+9)(x-6)= equation:

Simplifying
(x + 9)(x + -6) = 0

Reorder the terms:
(9 + x)(x + -6) = 0

Reorder the terms:
(9 + x)(-6 + x) = 0

Multiply (9 + x) * (-6 + x)
(9(-6 + x) + x(-6 + x)) = 0
((-6 * 9 + x * 9) + x(-6 + x)) = 0
((-54 + 9x) + x(-6 + x)) = 0
(-54 + 9x + (-6 * x + x * x)) = 0
(-54 + 9x + (-6x + x2)) = 0

Combine like terms: 9x + -6x = 3x
(-54 + 3x + x2) = 0

Solving
-54 + 3x + x2 = 0
