Simplifying d2 + -16d + -64 = 0 Reorder the terms: -64 + -16d + d2 = 0 Solving -64 + -16d + d2 = 0 Solving for variable 'd'. Begin completing the square. Move the constant term to the right: Add '64' to each side of the equation. -64 + -16d + 64 + d2 = 0 + 64 Reorder the terms: -64 + 64 + -16d + d2 = 0 + 64 Combine like terms: -64 + 64 = 0 0 + -16d + d2 = 0 + 64 -16d + d2 = 0 + 64 Combine like terms: 0 + 64 = 64 -16d + d2 = 64 The d term is -16d. Take half its coefficient (-8). Square it (64) and add it to both sides. Add '64' to each side of the equation. -16d + 64 + d2 = 64 + 64 Reorder the terms: 64 + -16d + d2 = 64 + 64 Combine like terms: 64 + 64 = 128 64 + -16d + d2 = 128 Factor a perfect square on the left side: (d + -8)(d + -8) = 128 Calculate the square root of the right side: 11.313708499 Break this problem into two subproblems by setting (d + -8) equal to 11.313708499 and -11.313708499.Subproblem 1
d + -8 = 11.313708499 Simplifying d + -8 = 11.313708499 Reorder the terms: -8 + d = 11.313708499 Solving -8 + d = 11.313708499 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + d = 11.313708499 + 8 Combine like terms: -8 + 8 = 0 0 + d = 11.313708499 + 8 d = 11.313708499 + 8 Combine like terms: 11.313708499 + 8 = 19.313708499 d = 19.313708499 Simplifying d = 19.313708499Subproblem 2
