Solution for (2x-1)x(x+3)=0 equation:

Simplifying
(2x + -1) * x(x + 3) = 0

Reorder the terms:
(-1 + 2x) * x(x + 3) = 0

Reorder the terms:
(-1 + 2x) * x(3 + x) = 0

Reorder the terms for easier multiplication:
x(-1 + 2x)(3 + x) = 0

Multiply (-1 + 2x) * (3 + x)
x(-1(3 + x) + 2x * (3 + x)) = 0
x((3 * -1 + x * -1) + 2x * (3 + x)) = 0
x((-3 + -1x) + 2x * (3 + x)) = 0
x(-3 + -1x + (3 * 2x + x * 2x)) = 0
x(-3 + -1x + (6x + 2x2)) = 0

Combine like terms: -1x + 6x = 5x
x(-3 + 5x + 2x2) = 0
(-3 * x + 5x * x + 2x2 * x) = 0
(-3x + 5x2 + 2x3) = 0

Solving
-3x + 5x2 + 2x3 = 0
