Simplifying d2 + -9d + 9 = -4 Reorder the terms: 9 + -9d + d2 = -4 Solving 9 + -9d + d2 = -4 Solving for variable 'd'. Reorder the terms: 9 + 4 + -9d + d2 = -4 + 4 Combine like terms: 9 + 4 = 13 13 + -9d + d2 = -4 + 4 Combine like terms: -4 + 4 = 0 13 + -9d + d2 = 0 Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + -9d + -13 + d2 = 0 + -13 Reorder the terms: 13 + -13 + -9d + d2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -9d + d2 = 0 + -13 -9d + d2 = 0 + -13 Combine like terms: 0 + -13 = -13 -9d + d2 = -13 The d term is -9d. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9d + 20.25 + d2 = -13 + 20.25 Reorder the terms: 20.25 + -9d + d2 = -13 + 20.25 Combine like terms: -13 + 20.25 = 7.25 20.25 + -9d + d2 = 7.25 Factor a perfect square on the left side: (d + -4.5)(d + -4.5) = 7.25 Calculate the square root of the right side: 2.692582404 Break this problem into two subproblems by setting (d + -4.5) equal to 2.692582404 and -2.692582404.Subproblem 1
d + -4.5 = 2.692582404 Simplifying d + -4.5 = 2.692582404 Reorder the terms: -4.5 + d = 2.692582404 Solving -4.5 + d = 2.692582404 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + d = 2.692582404 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + d = 2.692582404 + 4.5 d = 2.692582404 + 4.5 Combine like terms: 2.692582404 + 4.5 = 7.192582404 d = 7.192582404 Simplifying d = 7.192582404Subproblem 2
d + -4.5 = -2.692582404 Simplifying d + -4.5 = -2.692582404 Reorder the terms: -4.5 + d = -2.692582404 Solving -4.5 + d = -2.692582404 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + d = -2.692582404 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + d = -2.692582404 + 4.5 d = -2.692582404 + 4.5 Combine like terms: -2.692582404 + 4.5 = 1.807417596 d = 1.807417596 Simplifying d = 1.807417596Solution
The solution to the problem is based on the solutions from the subproblems. d = {7.192582404, 1.807417596}
