Simplifying dr2 + -2d + 12 = 12 Reorder the terms: 12 + -2d + dr2 = 12 Add '-12' to each side of the equation. 12 + -2d + -12 + dr2 = 12 + -12 Reorder the terms: 12 + -12 + -2d + dr2 = 12 + -12 Combine like terms: 12 + -12 = 0 0 + -2d + dr2 = 12 + -12 -2d + dr2 = 12 + -12 Combine like terms: 12 + -12 = 0 -2d + dr2 = 0 Solving -2d + dr2 = 0 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), 'd'. d(-2 + r2) = 0Subproblem 1
Set the factor 'd' equal to zero and attempt to solve: Simplifying d = 0 Solving d = 0 Move all terms containing d to the left, all other terms to the right. Simplifying d = 0Subproblem 2
Set the factor '(-2 + r2)' equal to zero and attempt to solve: Simplifying -2 + r2 = 0 Solving -2 + r2 = 0 Move all terms containing d to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + r2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + r2 = 0 + 2 r2 = 0 + 2 Combine like terms: 0 + 2 = 2 r2 = 2 Add '-1r2' to each side of the equation. r2 + -1r2 = 2 + -1r2 Combine like terms: r2 + -1r2 = 0 0 = 2 + -1r2 Simplifying 0 = 2 + -1r2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
