Simplifying 2x2 = x2 + x2 + 2x + 1 Reorder the terms: 2x2 = 1 + 2x + x2 + x2 Combine like terms: x2 + x2 = 2x2 2x2 = 1 + 2x + 2x2 Add '-2x2' to each side of the equation. 2x2 + -2x2 = 1 + 2x + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 0 = 1 + 2x + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 0 = 1 + 2x + 0 0 = 1 + 2x Solving 0 = 1 + 2x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. 0 + -2x = 1 + 2x + -2x Remove the zero: -2x = 1 + 2x + -2x Combine like terms: 2x + -2x = 0 -2x = 1 + 0 -2x = 1 Divide each side by '-2'. x = -0.5 Simplifying x = -0.5
