Simplifying r2 + 24r = 26 Reorder the terms: 24r + r2 = 26 Solving 24r + r2 = 26 Solving for variable 'r'. Reorder the terms: -26 + 24r + r2 = 26 + -26 Combine like terms: 26 + -26 = 0 -26 + 24r + r2 = 0 Begin completing the square. Move the constant term to the right: Add '26' to each side of the equation. -26 + 24r + 26 + r2 = 0 + 26 Reorder the terms: -26 + 26 + 24r + r2 = 0 + 26 Combine like terms: -26 + 26 = 0 0 + 24r + r2 = 0 + 26 24r + r2 = 0 + 26 Combine like terms: 0 + 26 = 26 24r + r2 = 26 The r term is 24r. Take half its coefficient (12). Square it (144) and add it to both sides. Add '144' to each side of the equation. 24r + 144 + r2 = 26 + 144 Reorder the terms: 144 + 24r + r2 = 26 + 144 Combine like terms: 26 + 144 = 170 144 + 24r + r2 = 170 Factor a perfect square on the left side: (r + 12)(r + 12) = 170 Calculate the square root of the right side: 13.03840481 Break this problem into two subproblems by setting (r + 12) equal to 13.03840481 and -13.03840481.Subproblem 1
r + 12 = 13.03840481 Simplifying r + 12 = 13.03840481 Reorder the terms: 12 + r = 13.03840481 Solving 12 + r = 13.03840481 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + r = 13.03840481 + -12 Combine like terms: 12 + -12 = 0 0 + r = 13.03840481 + -12 r = 13.03840481 + -12 Combine like terms: 13.03840481 + -12 = 1.03840481 r = 1.03840481 Simplifying r = 1.03840481Subproblem 2
r + 12 = -13.03840481 Simplifying r + 12 = -13.03840481 Reorder the terms: 12 + r = -13.03840481 Solving 12 + r = -13.03840481 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + r = -13.03840481 + -12 Combine like terms: 12 + -12 = 0 0 + r = -13.03840481 + -12 r = -13.03840481 + -12 Combine like terms: -13.03840481 + -12 = -25.03840481 r = -25.03840481 Simplifying r = -25.03840481Solution
