Simplifying x2 + 7x + 11 = x + 4 Reorder the terms: 11 + 7x + x2 = x + 4 Reorder the terms: 11 + 7x + x2 = 4 + x Solving 11 + 7x + x2 = 4 + x Solving for variable 'x'. Reorder the terms: 11 + -4 + 7x + -1x + x2 = 4 + x + -4 + -1x Combine like terms: 11 + -4 = 7 7 + 7x + -1x + x2 = 4 + x + -4 + -1x Combine like terms: 7x + -1x = 6x 7 + 6x + x2 = 4 + x + -4 + -1x Reorder the terms: 7 + 6x + x2 = 4 + -4 + x + -1x Combine like terms: 4 + -4 = 0 7 + 6x + x2 = 0 + x + -1x 7 + 6x + x2 = x + -1x Combine like terms: x + -1x = 0 7 + 6x + x2 = 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
The solution to the problem is based on the solutions from the subproblems. x = {-1.585786438, -4.414213562}
