Solution for (x-3)(x+3)=x(x-2)+x(x-3) equation:


Simplifying
(x + -3)(x + 3) = x(x + -2) + x(x + -3)

Reorder the terms:
(-3 + x)(x + 3) = x(x + -2) + x(x + -3)

Reorder the terms:
(-3 + x)(3 + x) = x(x + -2) + x(x + -3)

Multiply (-3 + x) * (3 + x)
(-3(3 + x) + x(3 + x)) = x(x + -2) + x(x + -3)
((3 * -3 + x * -3) + x(3 + x)) = x(x + -2) + x(x + -3)
((-9 + -3x) + x(3 + x)) = x(x + -2) + x(x + -3)
(-9 + -3x + (3 * x + x * x)) = x(x + -2) + x(x + -3)
(-9 + -3x + (3x + x2)) = x(x + -2) + x(x + -3)

Combine like terms: -3x + 3x = 0
(-9 + 0 + x2) = x(x + -2) + x(x + -3)
(-9 + x2) = x(x + -2) + x(x + -3)

Reorder the terms:
-9 + x2 = x(-2 + x) + x(x + -3)
-9 + x2 = (-2 * x + x * x) + x(x + -3)
-9 + x2 = (-2x + x2) + x(x + -3)

Reorder the terms:
-9 + x2 = -2x + x2 + x(-3 + x)
-9 + x2 = -2x + x2 + (-3 * x + x * x)
-9 + x2 = -2x + x2 + (-3x + x2)

Reorder the terms:
-9 + x2 = -2x + -3x + x2 + x2

Combine like terms: -2x + -3x = -5x
-9 + x2 = -5x + x2 + x2

Combine like terms: x2 + x2 = 2x2
-9 + x2 = -5x + 2x2

Solving
-9 + x2 = -5x + 2x2

Solving for variable 'x'.

Reorder the terms:
-9 + 5x + x2 + -2x2 = -5x + 2x2 + 5x + -2x2

Combine like terms: x2 + -2x2 = -1x2
-9 + 5x + -1x2 = -5x + 2x2 + 5x + -2x2

Reorder the terms:
-9 + 5x + -1x2 = -5x + 5x + 2x2 + -2x2

Combine like terms: -5x + 5x = 0
-9 + 5x + -1x2 = 0 + 2x2 + -2x2
-9 + 5x + -1x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
-9 + 5x + -1x2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
9 + -5x + x2 = 0

Move the constant term to the right:

Add '-9' to each side of the equation.
9 + -5x + -9 + x2 = 0 + -9

Reorder the terms:
9 + -9 + -5x + x2 = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -5x + x2 = 0 + -9
-5x + x2 = 0 + -9

Combine like terms: 0 + -9 = -9
-5x + x2 = -9

The x term is -5x.  Take half its coefficient (-2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
-5x + 6.25 + x2 = -9 + 6.25

Reorder the terms:
6.25 + -5x + x2 = -9 + 6.25

Combine like terms: -9 + 6.25 = -2.75
6.25 + -5x + x2 = -2.75

Factor a perfect square on the left side:
(x + -2.5)(x + -2.5) = -2.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
