(1x-4)(2x-1)=

Solution for (1x-4)(2x-1)= equation:

Simplifying
(1x + -4)(2x + -1) = 0

Reorder the terms:
(-4 + 1x)(2x + -1) = 0

Reorder the terms:
(-4 + 1x)(-1 + 2x) = 0

Multiply (-4 + 1x) * (-1 + 2x)
(-4(-1 + 2x) + 1x * (-1 + 2x)) = 0
((-1 * -4 + 2x * -4) + 1x * (-1 + 2x)) = 0
((4 + -8x) + 1x * (-1 + 2x)) = 0
(4 + -8x + (-1 * 1x + 2x * 1x)) = 0
(4 + -8x + (-1x + 2x2)) = 0

Combine like terms: -8x + -1x = -9x
(4 + -9x + 2x2) = 0

Solving
4 + -9x + 2x2 = 0
