x(x+2)=2(x+8)

Solution for x(x+2)=2(x+8) equation:

Simplifying
x(x + 2) = 2(x + 8)

Reorder the terms:
x(2 + x) = 2(x + 8)
(2 * x + x * x) = 2(x + 8)
(2x + x2) = 2(x + 8)

Reorder the terms:
2x + x2 = 2(8 + x)
2x + x2 = (8 * 2 + x * 2)
2x + x2 = (16 + 2x)

Add '-2x' to each side of the equation.
2x + -2x + x2 = 16 + 2x + -2x

Combine like terms: 2x + -2x = 0
0 + x2 = 16 + 2x + -2x
x2 = 16 + 2x + -2x

Combine like terms: 2x + -2x = 0
x2 = 16 + 0
x2 = 16

Solving
x2 = 16
