Simplifying 4r2 = 22r Solving 4r2 = 22r Solving for variable 'r'. Reorder the terms: -22r + 4r2 = 22r + -22r Combine like terms: 22r + -22r = 0 -22r + 4r2 = 0 Factor out the Greatest Common Factor (GCF), '2r'. 2r(-11 + 2r) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'r' equal to zero and attempt to solve: Simplifying r = 0 Solving r = 0 Move all terms containing r to the left, all other terms to the right. Simplifying r = 0Subproblem 2
Set the factor '(-11 + 2r)' equal to zero and attempt to solve: Simplifying -11 + 2r = 0 Solving -11 + 2r = 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 + 2r = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 2r = 0 + 11 2r = 0 + 11 Combine like terms: 0 + 11 = 11 2r = 11 Divide each side by '2'. r = 5.5 Simplifying r = 5.5Solution
r = {0, 5.5}
