Simplifying 7(d + -2) = 5d(d + 2) Reorder the terms: 7(-2 + d) = 5d(d + 2) (-2 * 7 + d * 7) = 5d(d + 2) (-14 + 7d) = 5d(d + 2) Reorder the terms: -14 + 7d = 5d(2 + d) -14 + 7d = (2 * 5d + d * 5d) -14 + 7d = (10d + 5d2) Solving -14 + 7d = 10d + 5d2 Solving for variable 'd'. Combine like terms: 7d + -10d = -3d -14 + -3d + -5d2 = 10d + 5d2 + -10d + -5d2 Reorder the terms: -14 + -3d + -5d2 = 10d + -10d + 5d2 + -5d2 Combine like terms: 10d + -10d = 0 -14 + -3d + -5d2 = 0 + 5d2 + -5d2 -14 + -3d + -5d2 = 5d2 + -5d2 Combine like terms: 5d2 + -5d2 = 0 -14 + -3d + -5d2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(14 + 3d + 5d2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(14 + 3d + 5d2)' equal to zero and attempt to solve: Simplifying 14 + 3d + 5d2 = 0 Solving 14 + 3d + 5d2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 2.8 + 0.6d + d2 = 0 Move the constant term to the right: Add '-2.8' to each side of the equation. 2.8 + 0.6d + -2.8 + d2 = 0 + -2.8 Reorder the terms: 2.8 + -2.8 + 0.6d + d2 = 0 + -2.8 Combine like terms: 2.8 + -2.8 = 0.0 0.0 + 0.6d + d2 = 0 + -2.8 0.6d + d2 = 0 + -2.8 Combine like terms: 0 + -2.8 = -2.8 0.6d + d2 = -2.8 The d term is 0.6d. Take half its coefficient (0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. 0.6d + 0.09 + d2 = -2.8 + 0.09 Reorder the terms: 0.09 + 0.6d + d2 = -2.8 + 0.09 Combine like terms: -2.8 + 0.09 = -2.71 0.09 + 0.6d + d2 = -2.71 Factor a perfect square on the left side: (d + 0.3)(d + 0.3) = -2.71 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
