Simplifying (d + 3)(d + -7) = 0 Reorder the terms: (3 + d)(d + -7) = 0 Reorder the terms: (3 + d)(-7 + d) = 0 Multiply (3 + d) * (-7 + d) (3(-7 + d) + d(-7 + d)) = 0 ((-7 * 3 + d * 3) + d(-7 + d)) = 0 ((-21 + 3d) + d(-7 + d)) = 0 (-21 + 3d + (-7 * d + d * d)) = 0 (-21 + 3d + (-7d + d2)) = 0 Combine like terms: 3d + -7d = -4d (-21 + -4d + d2) = 0 Solving -21 + -4d + d2 = 0 Solving for variable 'd'. Factor a trinomial. (-3 + -1d)(7 + -1d) = 0Subproblem 1
Set the factor '(-3 + -1d)' equal to zero and attempt to solve: Simplifying -3 + -1d = 0 Solving -3 + -1d = 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 + -1d = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1d = 0 + 3 -1d = 0 + 3 Combine like terms: 0 + 3 = 3 -1d = 3 Divide each side by '-1'. d = -3 Simplifying d = -3Subproblem 2
Set the factor '(7 + -1d)' equal to zero and attempt to solve: Simplifying 7 + -1d = 0 Solving 7 + -1d = 0 Move all terms containing d to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -1d = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1d = 0 + -7 -1d = 0 + -7 Combine like terms: 0 + -7 = -7 -1d = -7 Divide each side by '-1'. d = 7 Simplifying d = 7Solution
d = {-3, 7}
