Simplifying r2 + -12 + -7r = 0 Reorder the terms: -12 + -7r + r2 = 0 Solving -12 + -7r + r2 = 0 Solving for variable 'r'. Begin completing the square. Move the constant term to the right: Add '12' to each side of the equation. -12 + -7r + 12 + r2 = 0 + 12 Reorder the terms: -12 + 12 + -7r + r2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + -7r + r2 = 0 + 12 -7r + r2 = 0 + 12 Combine like terms: 0 + 12 = 12 -7r + r2 = 12 The r term is -7r. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7r + 12.25 + r2 = 12 + 12.25 Reorder the terms: 12.25 + -7r + r2 = 12 + 12.25 Combine like terms: 12 + 12.25 = 24.25 12.25 + -7r + r2 = 24.25 Factor a perfect square on the left side: (r + -3.5)(r + -3.5) = 24.25 Calculate the square root of the right side: 4.924428901 Break this problem into two subproblems by setting (r + -3.5) equal to 4.924428901 and -4.924428901.Subproblem 1
r + -3.5 = 4.924428901 Simplifying r + -3.5 = 4.924428901 Reorder the terms: -3.5 + r = 4.924428901 Solving -3.5 + r = 4.924428901 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + r = 4.924428901 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + r = 4.924428901 + 3.5 r = 4.924428901 + 3.5 Combine like terms: 4.924428901 + 3.5 = 8.424428901 r = 8.424428901 Simplifying r = 8.424428901Subproblem 2
r + -3.5 = -4.924428901 Simplifying r + -3.5 = -4.924428901 Reorder the terms: -3.5 + r = -4.924428901 Solving -3.5 + r = -4.924428901 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + r = -4.924428901 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + r = -4.924428901 + 3.5 r = -4.924428901 + 3.5 Combine like terms: -4.924428901 + 3.5 = -1.424428901 r = -1.424428901 Simplifying r = -1.424428901Solution
The solution to the problem is based on the solutions from the subproblems. r = {8.424428901, -1.424428901}
