Simplifying (2x + -1)(x + 1) = x(x + 2) Reorder the terms: (-1 + 2x)(x + 1) = x(x + 2) Reorder the terms: (-1 + 2x)(1 + x) = x(x + 2) Multiply (-1 + 2x) * (1 + x) (-1(1 + x) + 2x * (1 + x)) = x(x + 2) ((1 * -1 + x * -1) + 2x * (1 + x)) = x(x + 2) ((-1 + -1x) + 2x * (1 + x)) = x(x + 2) (-1 + -1x + (1 * 2x + x * 2x)) = x(x + 2) (-1 + -1x + (2x + 2x2)) = x(x + 2) Combine like terms: -1x + 2x = 1x (-1 + 1x + 2x2) = x(x + 2) Reorder the terms: -1 + 1x + 2x2 = x(2 + x) -1 + 1x + 2x2 = (2 * x + x * x) -1 + 1x + 2x2 = (2x + x2) Solving -1 + 1x + 2x2 = 2x + x2 Solving for variable 'x'. Reorder the terms: -1 + 1x + -2x + 2x2 + -1x2 = 2x + x2 + -2x + -1x2 Combine like terms: 1x + -2x = -1x -1 + -1x + 2x2 + -1x2 = 2x + x2 + -2x + -1x2 Combine like terms: 2x2 + -1x2 = 1x2 -1 + -1x + 1x2 = 2x + x2 + -2x + -1x2 Reorder the terms: -1 + -1x + 1x2 = 2x + -2x + x2 + -1x2 Combine like terms: 2x + -2x = 0 -1 + -1x + 1x2 = 0 + x2 + -1x2 -1 + -1x + 1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -1 + -1x + 1x2 = 0 Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + -1x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -1x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1x + x2 = 0 + 1 -1x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -1x + x2 = 1 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. -1x + 0.25 + x2 = 1 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 1 + 0.25 Combine like terms: 1 + 0.25 = 1.25 0.25 + -1x + x2 = 1.25 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 1.25 Calculate the square root of the right side: 1.118033989 Break this problem into two subproblems by setting (x + -0.5) equal to 1.118033989 and -1.118033989.Subproblem 1
x + -0.5 = 1.118033989 Simplifying x + -0.5 = 1.118033989 Reorder the terms: -0.5 + x = 1.118033989 Solving -0.5 + x = 1.118033989 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 1.118033989 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 1.118033989 + 0.5 x = 1.118033989 + 0.5 Combine like terms: 1.118033989 + 0.5 = 1.618033989 x = 1.618033989 Simplifying x = 1.618033989Subproblem 2
x + -0.5 = -1.118033989 Simplifying x + -0.5 = -1.118033989 Reorder the terms: -0.5 + x = -1.118033989 Solving -0.5 + x = -1.118033989 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -1.118033989 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -1.118033989 + 0.5 x = -1.118033989 + 0.5 Combine like terms: -1.118033989 + 0.5 = -0.618033989 x = -0.618033989 Simplifying x = -0.618033989Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.618033989, -0.618033989}
