(2x+5)(x-6)=0

Solution for (2x+5)(x-6)=0 equation:

Simplifying
(2x + 5)(x + -6) = 0

Reorder the terms:
(5 + 2x)(x + -6) = 0

Reorder the terms:
(5 + 2x)(-6 + x) = 0

Multiply (5 + 2x) * (-6 + x)
(5(-6 + x) + 2x * (-6 + x)) = 0
((-6 * 5 + x * 5) + 2x * (-6 + x)) = 0
((-30 + 5x) + 2x * (-6 + x)) = 0
(-30 + 5x + (-6 * 2x + x * 2x)) = 0
(-30 + 5x + (-12x + 2x2)) = 0

Combine like terms: 5x + -12x = -7x
(-30 + -7x + 2x2) = 0

Solving
-30 + -7x + 2x2 = 0
