Simplifying
2(x2 + x) = 2x
Reorder the terms:
2(x + x2) = 2x
(x * 2 + x2 * 2) = 2x
(2x + 2x2) = 2x
Add '-2x' to each side of the equation.
2x + -2x + 2x2 = 2x + -2x
Combine like terms: 2x + -2x = 0
0 + 2x2 = 2x + -2x
2x2 = 2x + -2x
Combine like terms: 2x + -2x = 0
2x2 = 0
Solving
2x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '2'.
x2 = 0
Simplifying
x2 = 0
Take the square root of each side:
x = {0}
