Solution for (x)(x-4)(x-13)=0 equation:


Simplifying
(x)(x + -4)(x + -13) = 0

Reorder the terms:
x(-4 + x)(x + -13) = 0

Reorder the terms:
x(-4 + x)(-13 + x) = 0

Multiply (-4 + x) * (-13 + x)
x(-4(-13 + x) + x(-13 + x)) = 0
x((-13 * -4 + x * -4) + x(-13 + x)) = 0
x((52 + -4x) + x(-13 + x)) = 0
x(52 + -4x + (-13 * x + x * x)) = 0
x(52 + -4x + (-13x + x2)) = 0

Combine like terms: -4x + -13x = -17x
x(52 + -17x + x2) = 0
(52 * x + -17x * x + x2 * x) = 0
(52x + -17x2 + x3) = 0

Solving
52x + -17x2 + x3 = 0

Solving for variable 'x'.
