Simplifying 6d2 + 21d + -30d + -35 = 0 Reorder the terms: -35 + 21d + -30d + 6d2 = 0 Combine like terms: 21d + -30d = -9d -35 + -9d + 6d2 = 0 Solving -35 + -9d + 6d2 = 0 Solving for variable 'd'. Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. -5.833333333 + -1.5d + d2 = 0 Move the constant term to the right: Add '5.833333333' to each side of the equation. -5.833333333 + -1.5d + 5.833333333 + d2 = 0 + 5.833333333 Reorder the terms: -5.833333333 + 5.833333333 + -1.5d + d2 = 0 + 5.833333333 Combine like terms: -5.833333333 + 5.833333333 = 0.000000000 0.000000000 + -1.5d + d2 = 0 + 5.833333333 -1.5d + d2 = 0 + 5.833333333 Combine like terms: 0 + 5.833333333 = 5.833333333 -1.5d + d2 = 5.833333333 The d term is -1.5d. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5d + 0.5625 + d2 = 5.833333333 + 0.5625 Reorder the terms: 0.5625 + -1.5d + d2 = 5.833333333 + 0.5625 Combine like terms: 5.833333333 + 0.5625 = 6.395833333 0.5625 + -1.5d + d2 = 6.395833333 Factor a perfect square on the left side: (d + -0.75)(d + -0.75) = 6.395833333 Calculate the square root of the right side: 2.528998484 Break this problem into two subproblems by setting (d + -0.75) equal to 2.528998484 and -2.528998484.Subproblem 1
d + -0.75 = 2.528998484 Simplifying d + -0.75 = 2.528998484 Reorder the terms: -0.75 + d = 2.528998484 Solving -0.75 + d = 2.528998484 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + d = 2.528998484 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + d = 2.528998484 + 0.75 d = 2.528998484 + 0.75 Combine like terms: 2.528998484 + 0.75 = 3.278998484 d = 3.278998484 Simplifying d = 3.278998484Subproblem 2
d + -0.75 = -2.528998484 Simplifying d + -0.75 = -2.528998484 Reorder the terms: -0.75 + d = -2.528998484 Solving -0.75 + d = -2.528998484 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + d = -2.528998484 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + d = -2.528998484 + 0.75 d = -2.528998484 + 0.75 Combine like terms: -2.528998484 + 0.75 = -1.778998484 d = -1.778998484 Simplifying d = -1.778998484Solution
