Simplifying d(7d + -3) = 0 Reorder the terms: d(-3 + 7d) = 0 (-3 * d + 7d * d) = 0 (-3d + 7d2) = 0 Solving -3d + 7d2 = 0 Solving for variable 'd'. Factor out the Greatest Common Factor (GCF), 'd'. d(-3 + 7d) = 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 '(-3 + 7d)' equal to zero and attempt to solve: Simplifying -3 + 7d = 0 Solving -3 + 7d = 0 Move all terms containing d to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 7d = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 7d = 0 + 3 7d = 0 + 3 Combine like terms: 0 + 3 = 3 7d = 3 Divide each side by '7'. d = 0.4285714286 Simplifying d = 0.4285714286Solution
d = {0, 0.4285714286}
