(x+6)(2x-1)=0

Solution for (x+6)(2x-1)=0 equation:

Simplifying
(x + 6)(2x + -1) = 0

Reorder the terms:
(6 + x)(2x + -1) = 0

Reorder the terms:
(6 + x)(-1 + 2x) = 0

Multiply (6 + x) * (-1 + 2x)
(6(-1 + 2x) + x(-1 + 2x)) = 0
((-1 * 6 + 2x * 6) + x(-1 + 2x)) = 0
((-6 + 12x) + x(-1 + 2x)) = 0
(-6 + 12x + (-1 * x + 2x * x)) = 0
(-6 + 12x + (-1x + 2x2)) = 0

Combine like terms: 12x + -1x = 11x
(-6 + 11x + 2x2) = 0

Solving
-6 + 11x + 2x2 = 0
