Solution for x^2=(x-2)*(x+6) equation:


Simplifying
x2 = (x + -2)(x + 6)

Reorder the terms:
x2 = (-2 + x)(x + 6)

Reorder the terms:
x2 = (-2 + x)(6 + x)

Multiply (-2 + x) * (6 + x)
x2 = (-2(6 + x) + x(6 + x))
x2 = ((6 * -2 + x * -2) + x(6 + x))
x2 = ((-12 + -2x) + x(6 + x))
x2 = (-12 + -2x + (6 * x + x * x))
x2 = (-12 + -2x + (6x + x2))

Combine like terms: -2x + 6x = 4x
x2 = (-12 + 4x + x2)

Add '-1x2' to each side of the equation.
x2 + -1x2 = -12 + 4x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
0 = -12 + 4x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
0 = -12 + 4x + 0
0 = -12 + 4x

Solving
0 = -12 + 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 = -12 + 4x + -4x
Remove the zero:
-4x = -12 + 4x + -4x

Combine like terms: 4x + -4x = 0
-4x = -12 + 0
-4x = -12

Divide each side by '-4'.
x = 3

Simplifying
x = 3
