Simplifying d2 + 11d = -3 Reorder the terms: 11d + d2 = -3 Solving 11d + d2 = -3 Solving for variable 'd'. Reorder the terms: 3 + 11d + d2 = -3 + 3 Combine like terms: -3 + 3 = 0 3 + 11d + d2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + 11d + -3 + d2 = 0 + -3 Reorder the terms: 3 + -3 + 11d + d2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 11d + d2 = 0 + -3 11d + d2 = 0 + -3 Combine like terms: 0 + -3 = -3 11d + d2 = -3 The d term is 11d. Take half its coefficient (5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. 11d + 30.25 + d2 = -3 + 30.25 Reorder the terms: 30.25 + 11d + d2 = -3 + 30.25 Combine like terms: -3 + 30.25 = 27.25 30.25 + 11d + d2 = 27.25 Factor a perfect square on the left side: (d + 5.5)(d + 5.5) = 27.25 Calculate the square root of the right side: 5.220153254 Break this problem into two subproblems by setting (d + 5.5) equal to 5.220153254 and -5.220153254.Subproblem 1
d + 5.5 = 5.220153254 Simplifying d + 5.5 = 5.220153254 Reorder the terms: 5.5 + d = 5.220153254 Solving 5.5 + d = 5.220153254 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + d = 5.220153254 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + d = 5.220153254 + -5.5 d = 5.220153254 + -5.5 Combine like terms: 5.220153254 + -5.5 = -0.279846746 d = -0.279846746 Simplifying d = -0.279846746Subproblem 2
d + 5.5 = -5.220153254 Simplifying d + 5.5 = -5.220153254 Reorder the terms: 5.5 + d = -5.220153254 Solving 5.5 + d = -5.220153254 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + d = -5.220153254 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + d = -5.220153254 + -5.5 d = -5.220153254 + -5.5 Combine like terms: -5.220153254 + -5.5 = -10.720153254 d = -10.720153254 Simplifying d = -10.720153254Solution
The solution to the problem is based on the solutions from the subproblems. d = {-0.279846746, -10.720153254}
