Solution for x*x=36+(x-2)*(x-2) equation:


Simplifying
x * x = 36 + (x + -2)(x + -2)

Multiply x * x
x2 = 36 + (x + -2)(x + -2)

Reorder the terms:
x2 = 36 + (-2 + x)(x + -2)

Reorder the terms:
x2 = 36 + (-2 + x)(-2 + x)

Multiply (-2 + x) * (-2 + x)
x2 = 36 + (-2(-2 + x) + x(-2 + x))
x2 = 36 + ((-2 * -2 + x * -2) + x(-2 + x))
x2 = 36 + ((4 + -2x) + x(-2 + x))
x2 = 36 + (4 + -2x + (-2 * x + x * x))
x2 = 36 + (4 + -2x + (-2x + x2))

Combine like terms: -2x + -2x = -4x
x2 = 36 + (4 + -4x + x2)

Combine like terms: 36 + 4 = 40
x2 = 40 + -4x + x2

Add '-1x2' to each side of the equation.
x2 + -1x2 = 40 + -4x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
0 = 40 + -4x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
0 = 40 + -4x + 0
0 = 40 + -4x

Solving
0 = 40 + -4x

Solving for variable 'x'.

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

Add '4x' to each side of the equation.
0 + 4x = 40 + -4x + 4x
Remove the zero:
4x = 40 + -4x + 4x

Combine like terms: -4x + 4x = 0
4x = 40 + 0
4x = 40

Divide each side by '4'.
x = 10

Simplifying
x = 10
