Simplifying 5d2 + -2d + -8 = 0 Reorder the terms: -8 + -2d + 5d2 = 0 Solving -8 + -2d + 5d2 = 0 Solving for variable 'd'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.6 + -0.4d + d2 = 0 Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + -0.4d + 1.6 + d2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + -0.4d + d2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + -0.4d + d2 = 0 + 1.6 -0.4d + d2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 -0.4d + d2 = 1.6 The d term is -0.4d. Take half its coefficient (-0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. -0.4d + 0.04 + d2 = 1.6 + 0.04 Reorder the terms: 0.04 + -0.4d + d2 = 1.6 + 0.04 Combine like terms: 1.6 + 0.04 = 1.64 0.04 + -0.4d + d2 = 1.64 Factor a perfect square on the left side: (d + -0.2)(d + -0.2) = 1.64 Calculate the square root of the right side: 1.280624847 Break this problem into two subproblems by setting (d + -0.2) equal to 1.280624847 and -1.280624847.Subproblem 1
d + -0.2 = 1.280624847 Simplifying d + -0.2 = 1.280624847 Reorder the terms: -0.2 + d = 1.280624847 Solving -0.2 + d = 1.280624847 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + d = 1.280624847 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + d = 1.280624847 + 0.2 d = 1.280624847 + 0.2 Combine like terms: 1.280624847 + 0.2 = 1.480624847 d = 1.480624847 Simplifying d = 1.480624847Subproblem 2
d + -0.2 = -1.280624847 Simplifying d + -0.2 = -1.280624847 Reorder the terms: -0.2 + d = -1.280624847 Solving -0.2 + d = -1.280624847 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + d = -1.280624847 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + d = -1.280624847 + 0.2 d = -1.280624847 + 0.2 Combine like terms: -1.280624847 + 0.2 = -1.080624847 d = -1.080624847 Simplifying d = -1.080624847Solution
