Simplifying 2r2 + 4r + -198 = 0 Reorder the terms: -198 + 4r + 2r2 = 0 Solving -198 + 4r + 2r2 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), '2'. 2(-99 + 2r + r2) = 0 Factor a trinomial. 2((-11 + -1r)(9 + -1r)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-11 + -1r)' equal to zero and attempt to solve: Simplifying -11 + -1r = 0 Solving -11 + -1r = 0 Move all terms containing r to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + -1r = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -1r = 0 + 11 -1r = 0 + 11 Combine like terms: 0 + 11 = 11 -1r = 11 Divide each side by '-1'. r = -11 Simplifying r = -11Subproblem 2
Set the factor '(9 + -1r)' equal to zero and attempt to solve: Simplifying 9 + -1r = 0 Solving 9 + -1r = 0 Move all terms containing r to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1r = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1r = 0 + -9 -1r = 0 + -9 Combine like terms: 0 + -9 = -9 -1r = -9 Divide each side by '-1'. r = 9 Simplifying r = 9Solution
r = {-11, 9}
