Simplifying -1d2 + -3d + 7 = 0 Reorder the terms: 7 + -3d + -1d2 = 0 Solving 7 + -3d + -1d2 = 0 Solving for variable 'd'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -7 + 3d + d2 = 0 Move the constant term to the right: Add '7' to each side of the equation. -7 + 3d + 7 + d2 = 0 + 7 Reorder the terms: -7 + 7 + 3d + d2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 3d + d2 = 0 + 7 3d + d2 = 0 + 7 Combine like terms: 0 + 7 = 7 3d + d2 = 7 The d term is 3d. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3d + 2.25 + d2 = 7 + 2.25 Reorder the terms: 2.25 + 3d + d2 = 7 + 2.25 Combine like terms: 7 + 2.25 = 9.25 2.25 + 3d + d2 = 9.25 Factor a perfect square on the left side: (d + 1.5)(d + 1.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (d + 1.5) equal to 3.041381265 and -3.041381265.Subproblem 1
d + 1.5 = 3.041381265 Simplifying d + 1.5 = 3.041381265 Reorder the terms: 1.5 + d = 3.041381265 Solving 1.5 + d = 3.041381265 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + d = 3.041381265 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + d = 3.041381265 + -1.5 d = 3.041381265 + -1.5 Combine like terms: 3.041381265 + -1.5 = 1.541381265 d = 1.541381265 Simplifying d = 1.541381265Subproblem 2
d + 1.5 = -3.041381265 Simplifying d + 1.5 = -3.041381265 Reorder the terms: 1.5 + d = -3.041381265 Solving 1.5 + d = -3.041381265 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + d = -3.041381265 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + d = -3.041381265 + -1.5 d = -3.041381265 + -1.5 Combine like terms: -3.041381265 + -1.5 = -4.541381265 d = -4.541381265 Simplifying d = -4.541381265Solution
The solution to the problem is based on the solutions from the subproblems. d = {1.541381265, -4.541381265}
