Solution for x^2+x-12=(x-a)(x-b) equation:


Simplifying
x2 + x + -12 = (x + -1a)(x + -1b)

Reorder the terms:
-12 + x + x2 = (x + -1a)(x + -1b)

Reorder the terms:
-12 + x + x2 = (-1a + x)(x + -1b)

Reorder the terms:
-12 + x + x2 = (-1a + x)(-1b + x)

Multiply (-1a + x) * (-1b + x)
-12 + x + x2 = (-1a * (-1b + x) + x(-1b + x))
-12 + x + x2 = ((-1b * -1a + x * -1a) + x(-1b + x))
-12 + x + x2 = ((1ab + -1ax) + x(-1b + x))
-12 + x + x2 = (1ab + -1ax + (-1b * x + x * x))
-12 + x + x2 = (1ab + -1ax + (-1bx + x2))
-12 + x + x2 = (1ab + -1ax + -1bx + x2)

Add '-1x2' to each side of the equation.
-12 + x + x2 + -1x2 = 1ab + -1ax + -1bx + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-12 + x + 0 = 1ab + -1ax + -1bx + x2 + -1x2
-12 + x = 1ab + -1ax + -1bx + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-12 + x = 1ab + -1ax + -1bx + 0
-12 + x = 1ab + -1ax + -1bx

Solving
-12 + x = 1ab + -1ax + -1bx

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.
