Solution for (3-x)*(4x^2-x+0)=0 equation:


Simplifying
(3 + -1x)(4x2 + -1x + 0) = 0

Reorder the terms:
(3 + -1x)(0 + -1x + 4x2) = 0
Remove the zero:
(3 + -1x)(-1x + 4x2) = 0

Multiply (3 + -1x) * (-1x + 4x2)
(3(-1x + 4x2) + -1x * (-1x + 4x2)) = 0
((-1x * 3 + 4x2 * 3) + -1x * (-1x + 4x2)) = 0
((-3x + 12x2) + -1x * (-1x + 4x2)) = 0
(-3x + 12x2 + (-1x * -1x + 4x2 * -1x)) = 0
(-3x + 12x2 + (1x2 + -4x3)) = 0

Combine like terms: 12x2 + 1x2 = 13x2
(-3x + 13x2 + -4x3) = 0

Solving
-3x + 13x2 + -4x3 = 0
