Simplifying 20r2 + 7 = 45r + 7 Reorder the terms: 7 + 20r2 = 45r + 7 Reorder the terms: 7 + 20r2 = 7 + 45r Add '-7' to each side of the equation. 7 + -7 + 20r2 = 7 + -7 + 45r Combine like terms: 7 + -7 = 0 0 + 20r2 = 7 + -7 + 45r 20r2 = 7 + -7 + 45r Combine like terms: 7 + -7 = 0 20r2 = 0 + 45r 20r2 = 45r Solving 20r2 = 45r Solving for variable 'r'. Reorder the terms: -45r + 20r2 = 45r + -45r Combine like terms: 45r + -45r = 0 -45r + 20r2 = 0 Factor out the Greatest Common Factor (GCF), '5r'. 5r(-9 + 4r) = 0 Ignore the factor 5.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 '(-9 + 4r)' equal to zero and attempt to solve: Simplifying -9 + 4r = 0 Solving -9 + 4r = 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 + 4r = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 4r = 0 + 9 4r = 0 + 9 Combine like terms: 0 + 9 = 9 4r = 9 Divide each side by '4'. r = 2.25 Simplifying r = 2.25Solution
r = {0, 2.25}
