Simplifying
x(x + 2) = 2x + 9
Reorder the terms:
x(2 + x) = 2x + 9
(2 * x + x * x) = 2x + 9
(2x + x2) = 2x + 9
Reorder the terms:
2x + x2 = 9 + 2x
Add '-2x' to each side of the equation.
2x + -2x + x2 = 9 + 2x + -2x
Combine like terms: 2x + -2x = 0
0 + x2 = 9 + 2x + -2x
x2 = 9 + 2x + -2x
Combine like terms: 2x + -2x = 0
x2 = 9 + 0
x2 = 9
Solving
x2 = 9
