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


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

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

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

Multiply (-1a + x) * (-1c + x)
(-1a * (-1c + x) + x(-1c + x)) + -1b = 0
((-1c * -1a + x * -1a) + x(-1c + x)) + -1b = 0
((1ac + -1ax) + x(-1c + x)) + -1b = 0
(1ac + -1ax + (-1c * x + x * x)) + -1b = 0
(1ac + -1ax + (-1cx + x2)) + -1b = 0
(1ac + -1ax + -1cx + x2) + -1b = 0

Reorder the terms:
1ac + -1ax + -1b + -1cx + x2 = 0

Solving
1ac + -1ax + -1b + -1cx + x2 = 0

Solving for variable 'a'.

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

Add 'b' to each side of the equation.
1ac + -1ax + -1b + -1cx + b + x2 = 0 + b

Reorder the terms:
1ac + -1ax + -1b + b + -1cx + x2 = 0 + b

Combine like terms: -1b + b = 0
1ac + -1ax + 0 + -1cx + x2 = 0 + b
1ac + -1ax + -1cx + x2 = 0 + b
Remove the zero:
1ac + -1ax + -1cx + x2 = b

Add 'cx' to each side of the equation.
1ac + -1ax + -1cx + cx + x2 = b + cx

Combine like terms: -1cx + cx = 0
1ac + -1ax + 0 + x2 = b + cx
1ac + -1ax + x2 = b + cx

Add '-1x2' to each side of the equation.
1ac + -1ax + x2 + -1x2 = b + cx + -1x2

Combine like terms: x2 + -1x2 = 0
1ac + -1ax + 0 = b + cx + -1x2
1ac + -1ax = b + cx + -1x2

Reorder the terms:
1ac + -1ax + -1b + -1cx + x2 = b + -1b + cx + -1cx + -1x2 + x2

Combine like terms: b + -1b = 0
1ac + -1ax + -1b + -1cx + x2 = 0 + cx + -1cx + -1x2 + x2
1ac + -1ax + -1b + -1cx + x2 = cx + -1cx + -1x2 + x2

Combine like terms: cx + -1cx = 0
1ac + -1ax + -1b + -1cx + x2 = 0 + -1x2 + x2
1ac + -1ax + -1b + -1cx + x2 = -1x2 + x2

Combine like terms: -1x2 + x2 = 0
1ac + -1ax + -1b + -1cx + x2 = 0
