Simplifying x2 + 16x = -42 Reorder the terms: 16x + x2 = -42 Solving 16x + x2 = -42 Solving for variable 'x'. Reorder the terms: 42 + 16x + x2 = -42 + 42 Combine like terms: -42 + 42 = 0 42 + 16x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-42' to each side of the equation. 42 + 16x + -42 + x2 = 0 + -42 Reorder the terms: 42 + -42 + 16x + x2 = 0 + -42 Combine like terms: 42 + -42 = 0 0 + 16x + x2 = 0 + -42 16x + x2 = 0 + -42 Combine like terms: 0 + -42 = -42 16x + x2 = -42 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 = -42 + 64 Reorder the terms: 64 + 16x + x2 = -42 + 64 Combine like terms: -42 + 64 = 22 64 + 16x + x2 = 22 Factor a perfect square on the left side: (x + 8)(x + 8) = 22 Calculate the square root of the right side: 4.69041576 Break this problem into two subproblems by setting (x + 8) equal to 4.69041576 and -4.69041576.Subproblem 1
x + 8 = 4.69041576 Simplifying x + 8 = 4.69041576 Reorder the terms: 8 + x = 4.69041576 Solving 8 + x = 4.69041576 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 = 4.69041576 + -8 Combine like terms: 8 + -8 = 0 0 + x = 4.69041576 + -8 x = 4.69041576 + -8 Combine like terms: 4.69041576 + -8 = -3.30958424 x = -3.30958424 Simplifying x = -3.30958424Subproblem 2
x + 8 = -4.69041576 Simplifying x + 8 = -4.69041576 Reorder the terms: 8 + x = -4.69041576 Solving 8 + x = -4.69041576 Solving for variable 'x'.
