Simplifying 2r(r + -7) + 8r = 56 Reorder the terms: 2r(-7 + r) + 8r = 56 (-7 * 2r + r * 2r) + 8r = 56 (-14r + 2r2) + 8r = 56 Reorder the terms: -14r + 8r + 2r2 = 56 Combine like terms: -14r + 8r = -6r -6r + 2r2 = 56 Solving -6r + 2r2 = 56 Solving for variable 'r'. Reorder the terms: -56 + -6r + 2r2 = 56 + -56 Combine like terms: 56 + -56 = 0 -56 + -6r + 2r2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-28 + -3r + r2) = 0 Factor a trinomial. 2((-4 + -1r)(7 + -1r)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-4 + -1r)' equal to zero and attempt to solve: Simplifying -4 + -1r = 0 Solving -4 + -1r = 0 Move all terms containing r to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + -1r = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -1r = 0 + 4 -1r = 0 + 4 Combine like terms: 0 + 4 = 4 -1r = 4 Divide each side by '-1'. r = -4 Simplifying r = -4Subproblem 2
Set the factor '(7 + -1r)' equal to zero and attempt to solve: Simplifying 7 + -1r = 0 Solving 7 + -1r = 0 Move all terms containing r to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -1r = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1r = 0 + -7 -1r = 0 + -7 Combine like terms: 0 + -7 = -7 -1r = -7 Divide each side by '-1'. r = 7 Simplifying r = 7Solution
r = {-4, 7}
