(x-4)(3x-1)=0

Solution for (x-4)(3x-1)=0 equation:

Simplifying
(x + -4)(3x + -1) = 0

Reorder the terms:
(-4 + x)(3x + -1) = 0

Reorder the terms:
(-4 + x)(-1 + 3x) = 0

Multiply (-4 + x) * (-1 + 3x)
(-4(-1 + 3x) + x(-1 + 3x)) = 0
((-1 * -4 + 3x * -4) + x(-1 + 3x)) = 0
((4 + -12x) + x(-1 + 3x)) = 0
(4 + -12x + (-1 * x + 3x * x)) = 0
(4 + -12x + (-1x + 3x2)) = 0

Combine like terms: -12x + -1x = -13x
(4 + -13x + 3x2) = 0

Solving
4 + -13x + 3x2 = 0
