Simplifying d2 + -10d + 1 = 0 Reorder the terms: 1 + -10d + d2 = 0 Solving 1 + -10d + d2 = 0 Solving for variable 'd'. Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + -10d + -1 + d2 = 0 + -1 Reorder the terms: 1 + -1 + -10d + d2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -10d + d2 = 0 + -1 -10d + d2 = 0 + -1 Combine like terms: 0 + -1 = -1 -10d + d2 = -1 The d term is -10d. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10d + 25 + d2 = -1 + 25 Reorder the terms: 25 + -10d + d2 = -1 + 25 Combine like terms: -1 + 25 = 24 25 + -10d + d2 = 24 Factor a perfect square on the left side: (d + -5)(d + -5) = 24 Calculate the square root of the right side: 4.898979486 Break this problem into two subproblems by setting (d + -5) equal to 4.898979486 and -4.898979486.Subproblem 1
d + -5 = 4.898979486 Simplifying d + -5 = 4.898979486 Reorder the terms: -5 + d = 4.898979486 Solving -5 + d = 4.898979486 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + d = 4.898979486 + 5 Combine like terms: -5 + 5 = 0 0 + d = 4.898979486 + 5 d = 4.898979486 + 5 Combine like terms: 4.898979486 + 5 = 9.898979486 d = 9.898979486 Simplifying d = 9.898979486Subproblem 2
