Simplifying x2 + 16x = -3 Reorder the terms: 16x + x2 = -3 Solving 16x + x2 = -3 Solving for variable 'x'. Reorder the terms: 3 + 16x + x2 = -3 + 3 Combine like terms: -3 + 3 = 0 3 + 16x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + 16x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + 16x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 16x + x2 = 0 + -3 16x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 16x + x2 = -3 The x term is 16x. Take half its coefficient (8). Square it (64) and add it to both sides. Add '64' to each side of the equation. 16x + 64 + x2 = -3 + 64 Reorder the terms: 64 + 16x + x2 = -3 + 64 Combine like terms: -3 + 64 = 61 64 + 16x + x2 = 61 Factor a perfect square on the left side: (x + 8)(x + 8) = 61 Calculate the square root of the right side: 7.810249676 Break this problem into two subproblems by setting (x + 8) equal to 7.810249676 and -7.810249676.Subproblem 1
x + 8 = 7.810249676 Simplifying x + 8 = 7.810249676 Reorder the terms: 8 + x = 7.810249676 Solving 8 + x = 7.810249676 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = 7.810249676 + -8 Combine like terms: 8 + -8 = 0 0 + x = 7.810249676 + -8 x = 7.810249676 + -8 Combine like terms: 7.810249676 + -8 = -0.189750324 x = -0.189750324 Simplifying x = -0.189750324Subproblem 2
x + 8 = -7.810249676 Simplifying x + 8 = -7.810249676 Reorder the terms: 8 + x = -7.810249676 Solving 8 + x = -7.810249676 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = -7.810249676 + -8 Combine like terms: 8 + -8 = 0 0 + x = -7.810249676 + -8 x = -7.810249676 + -8 Combine like terms: -7.810249676 + -8 = -15.810249676 x = -15.810249676 Simplifying x = -15.810249676Solution
