X^2-(a+b)+ab=0

Solution for X^2-(a+b)+ab=0 equation:

Simplifying
X2 + -1(a + b) + ab = 0
X2 + (a * -1 + b * -1) + ab = 0
X2 + (-1a + -1b) + ab = 0

Reorder the terms:
X2 + -1a + ab + -1b = 0

Solving
X2 + -1a + ab + -1b = 0

Solving for variable 'X'.

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

Add 'a' to each side of the equation.
X2 + -1a + ab + a + -1b = 0 + a

Reorder the terms:
X2 + -1a + a + ab + -1b = 0 + a

Combine like terms: -1a + a = 0
X2 + 0 + ab + -1b = 0 + a
X2 + ab + -1b = 0 + a
Remove the zero:
X2 + ab + -1b = a

Add '-1ab' to each side of the equation.
X2 + ab + -1ab + -1b = a + -1ab

Combine like terms: ab + -1ab = 0
X2 + 0 + -1b = a + -1ab
X2 + -1b = a + -1ab

Add 'b' to each side of the equation.
X2 + -1b + b = a + -1ab + b

Combine like terms: -1b + b = 0
X2 + 0 = a + -1ab + b
X2 = a + -1ab + b

Simplifying
X2 = a + -1ab + b

Reorder the terms:
X2 + -1a + ab + -1b = a + -1a + -1ab + ab + b + -1b

Combine like terms: a + -1a = 0
X2 + -1a + ab + -1b = 0 + -1ab + ab + b + -1b
X2 + -1a + ab + -1b = -1ab + ab + b + -1b

Combine like terms: -1ab + ab = 0
X2 + -1a + ab + -1b = 0 + b + -1b
X2 + -1a + ab + -1b = b + -1b

Combine like terms: b + -1b = 0
X2 + -1a + ab + -1b = 0
