Simplifying 2x2 + 4x + 9 = x2 + -2x + 2 Reorder the terms: 9 + 4x + 2x2 = x2 + -2x + 2 Reorder the terms: 9 + 4x + 2x2 = 2 + -2x + x2 Solving 9 + 4x + 2x2 = 2 + -2x + x2 Solving for variable 'x'. Reorder the terms: 9 + -2 + 4x + 2x + 2x2 + -1x2 = 2 + -2x + x2 + -2 + 2x + -1x2 Combine like terms: 9 + -2 = 7 7 + 4x + 2x + 2x2 + -1x2 = 2 + -2x + x2 + -2 + 2x + -1x2 Combine like terms: 4x + 2x = 6x 7 + 6x + 2x2 + -1x2 = 2 + -2x + x2 + -2 + 2x + -1x2 Combine like terms: 2x2 + -1x2 = 1x2 7 + 6x + 1x2 = 2 + -2x + x2 + -2 + 2x + -1x2 Reorder the terms: 7 + 6x + 1x2 = 2 + -2 + -2x + 2x + x2 + -1x2 Combine like terms: 2 + -2 = 0 7 + 6x + 1x2 = 0 + -2x + 2x + x2 + -1x2 7 + 6x + 1x2 = -2x + 2x + x2 + -1x2 Combine like terms: -2x + 2x = 0 7 + 6x + 1x2 = 0 + x2 + -1x2 7 + 6x + 1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 7 + 6x + 1x2 = 0 Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + 6x + -7 + x2 = 0 + -7 Reorder the terms: 7 + -7 + 6x + x2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 6x + x2 = 0 + -7 6x + x2 = 0 + -7 Combine like terms: 0 + -7 = -7 6x + x2 = -7 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = -7 + 9 Reorder the terms: 9 + 6x + x2 = -7 + 9 Combine like terms: -7 + 9 = 2 9 + 6x + x2 = 2 Factor a perfect square on the left side: (x + 3)(x + 3) = 2 Calculate the square root of the right side: 1.414213562 Break this problem into two subproblems by setting (x + 3) equal to 1.414213562 and -1.414213562.Subproblem 1
x + 3 = 1.414213562 Simplifying x + 3 = 1.414213562 Reorder the terms: 3 + x = 1.414213562 Solving 3 + x = 1.414213562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 1.414213562 + -3 Combine like terms: 3 + -3 = 0 0 + x = 1.414213562 + -3 x = 1.414213562 + -3 Combine like terms: 1.414213562 + -3 = -1.585786438 x = -1.585786438 Simplifying x = -1.585786438Subproblem 2
x + 3 = -1.414213562 Simplifying x + 3 = -1.414213562 Reorder the terms: 3 + x = -1.414213562 Solving 3 + x = -1.414213562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -1.414213562 + -3 Combine like terms: 3 + -3 = 0 0 + x = -1.414213562 + -3 x = -1.414213562 + -3 Combine like terms: -1.414213562 + -3 = -4.414213562 x = -4.414213562 Simplifying x = -4.414213562Solution
