Solution for (x+a)(3x-b)=0 equation:


Simplifying
(x + a)(3x + -1b) = 0

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

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

Multiply (a + x) * (-1b + 3x)
(a(-1b + 3x) + x(-1b + 3x)) = 0
((-1b * a + 3x * a) + x(-1b + 3x)) = 0
((-1ab + 3ax) + x(-1b + 3x)) = 0
(-1ab + 3ax + (-1b * x + 3x * x)) = 0
(-1ab + 3ax + (-1bx + 3x2)) = 0
(-1ab + 3ax + -1bx + 3x2) = 0
