Simplifying 5r(2r + -5) = 5r + -9 Reorder the terms: 5r(-5 + 2r) = 5r + -9 (-5 * 5r + 2r * 5r) = 5r + -9 (-25r + 10r2) = 5r + -9 Reorder the terms: -25r + 10r2 = -9 + 5r Solving -25r + 10r2 = -9 + 5r Solving for variable 'r'. Reorder the terms: 9 + -25r + -5r + 10r2 = -9 + 5r + 9 + -5r Combine like terms: -25r + -5r = -30r 9 + -30r + 10r2 = -9 + 5r + 9 + -5r Reorder the terms: 9 + -30r + 10r2 = -9 + 9 + 5r + -5r Combine like terms: -9 + 9 = 0 9 + -30r + 10r2 = 0 + 5r + -5r 9 + -30r + 10r2 = 5r + -5r Combine like terms: 5r + -5r = 0 9 + -30r + 10r2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.9 + -3r + r2 = 0.0 Move the constant term to the right: Add '-0.9' to each side of the equation. 0.9 + -3r + -0.9 + r2 = 0.0 + -0.9 Reorder the terms: 0.9 + -0.9 + -3r + r2 = 0.0 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + -3r + r2 = 0.0 + -0.9 -3r + r2 = 0.0 + -0.9 Combine like terms: 0.0 + -0.9 = -0.9 -3r + r2 = -0.9 The r term is -3r. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3r + 2.25 + r2 = -0.9 + 2.25 Reorder the terms: 2.25 + -3r + r2 = -0.9 + 2.25 Combine like terms: -0.9 + 2.25 = 1.35 2.25 + -3r + r2 = 1.35 Factor a perfect square on the left side: (r + -1.5)(r + -1.5) = 1.35 Calculate the square root of the right side: 1.161895004 Break this problem into two subproblems by setting (r + -1.5) equal to 1.161895004 and -1.161895004.Subproblem 1
r + -1.5 = 1.161895004 Simplifying r + -1.5 = 1.161895004 Reorder the terms: -1.5 + r = 1.161895004 Solving -1.5 + r = 1.161895004 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + r = 1.161895004 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + r = 1.161895004 + 1.5 r = 1.161895004 + 1.5 Combine like terms: 1.161895004 + 1.5 = 2.661895004 r = 2.661895004 Simplifying r = 2.661895004Subproblem 2
r + -1.5 = -1.161895004 Simplifying r + -1.5 = -1.161895004 Reorder the terms: -1.5 + r = -1.161895004 Solving -1.5 + r = -1.161895004 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + r = -1.161895004 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + r = -1.161895004 + 1.5 r = -1.161895004 + 1.5 Combine like terms: -1.161895004 + 1.5 = 0.338104996 r = 0.338104996 Simplifying r = 0.338104996Solution
The solution to the problem is based on the solutions from the subproblems. r = {2.661895004, 0.338104996}
