Simplifying (x + 1)(x + 2) = 2x Reorder the terms: (1 + x)(x + 2) = 2x Reorder the terms: (1 + x)(2 + x) = 2x Multiply (1 + x) * (2 + x) (1(2 + x) + x(2 + x)) = 2x ((2 * 1 + x * 1) + x(2 + x)) = 2x ((2 + 1x) + x(2 + x)) = 2x (2 + 1x + (2 * x + x * x)) = 2x (2 + 1x + (2x + x2)) = 2x Combine like terms: 1x + 2x = 3x (2 + 3x + x2) = 2x Solving 2 + 3x + x2 = 2x Solving for variable 'x'. Reorder the terms: 2 + 3x + -2x + x2 = 2x + -2x Combine like terms: 3x + -2x = 1x 2 + 1x + x2 = 2x + -2x Combine like terms: 2x + -2x = 0 2 + 1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + 1x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + 1x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 1x + x2 = 0 + -2 1x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 1x + x2 = -2 The x term is 1x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = -2 + 0.25 Reorder the terms: 0.25 + x + x2 = -2 + 0.25 Combine like terms: -2 + 0.25 = -1.75 0.25 + x + x2 = -1.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -1.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
