Simplifying 4d2 + 16d + 16 = 0 Reorder the terms: 16 + 16d + 4d2 = 0 Solving 16 + 16d + 4d2 = 0 Solving for variable 'd'. Factor out the Greatest Common Factor (GCF), '4'. 4(4 + 4d + d2) = 0 Factor a trinomial. 4((2 + d)(2 + d)) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(2 + d)' equal to zero and attempt to solve: Simplifying 2 + d = 0 Solving 2 + d = 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 + d = 0 + -2 Combine like terms: 2 + -2 = 0 0 + d = 0 + -2 d = 0 + -2 Combine like terms: 0 + -2 = -2 d = -2 Simplifying d = -2Subproblem 2
