Simplifying d2 + -28d = 9 Reorder the terms: -28d + d2 = 9 Solving -28d + d2 = 9 Solving for variable 'd'. Reorder the terms: -9 + -28d + d2 = 9 + -9 Combine like terms: 9 + -9 = 0 -9 + -28d + d2 = 0 Begin completing the square. Move the constant term to the right: Add '9' to each side of the equation. -9 + -28d + 9 + d2 = 0 + 9 Reorder the terms: -9 + 9 + -28d + d2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -28d + d2 = 0 + 9 -28d + d2 = 0 + 9 Combine like terms: 0 + 9 = 9 -28d + d2 = 9 The d term is -28d. Take half its coefficient (-14). Square it (196) and add it to both sides. Add '196' to each side of the equation. -28d + 196 + d2 = 9 + 196 Reorder the terms: 196 + -28d + d2 = 9 + 196 Combine like terms: 9 + 196 = 205 196 + -28d + d2 = 205 Factor a perfect square on the left side: (d + -14)(d + -14) = 205 Calculate the square root of the right side: 14.317821063 Break this problem into two subproblems by setting (d + -14) equal to 14.317821063 and -14.317821063.Subproblem 1
d + -14 = 14.317821063 Simplifying d + -14 = 14.317821063 Reorder the terms: -14 + d = 14.317821063 Solving -14 + d = 14.317821063 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '14' to each side of the equation. -14 + 14 + d = 14.317821063 + 14 Combine like terms: -14 + 14 = 0 0 + d = 14.317821063 + 14 d = 14.317821063 + 14 Combine like terms: 14.317821063 + 14 = 28.317821063 d = 28.317821063 Simplifying d = 28.317821063Subproblem 2
d + -14 = -14.317821063 Simplifying d + -14 = -14.317821063 Reorder the terms: -14 + d = -14.317821063 Solving -14 + d = -14.317821063 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '14' to each side of the equation. -14 + 14 + d = -14.317821063 + 14 Combine like terms: -14 + 14 = 0 0 + d = -14.317821063 + 14 d = -14.317821063 + 14 Combine like terms: -14.317821063 + 14 = -0.317821063 d = -0.317821063 Simplifying d = -0.317821063Solution
The solution to the problem is based on the solutions from the subproblems. d = {28.317821063, -0.317821063}
