(2x-11)(x+3)=0

Solution for (2x-11)(x+3)=0 equation:

Simplifying
(2x + -11)(x + 3) = 0

Reorder the terms:
(-11 + 2x)(x + 3) = 0

Reorder the terms:
(-11 + 2x)(3 + x) = 0

Multiply (-11 + 2x) * (3 + x)
(-11(3 + x) + 2x * (3 + x)) = 0
((3 * -11 + x * -11) + 2x * (3 + x)) = 0
((-33 + -11x) + 2x * (3 + x)) = 0
(-33 + -11x + (3 * 2x + x * 2x)) = 0
(-33 + -11x + (6x + 2x2)) = 0

Combine like terms: -11x + 6x = -5x
