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

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

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

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

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

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