Simplifying r2 + 14r + 25 = 0 Reorder the terms: 25 + 14r + r2 = 0 Solving 25 + 14r + r2 = 0 Solving for variable 'r'. Begin completing the square. Move the constant term to the right: Add '-25' to each side of the equation. 25 + 14r + -25 + r2 = 0 + -25 Reorder the terms: 25 + -25 + 14r + r2 = 0 + -25 Combine like terms: 25 + -25 = 0 0 + 14r + r2 = 0 + -25 14r + r2 = 0 + -25 Combine like terms: 0 + -25 = -25 14r + r2 = -25 The r term is 14r. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14r + 49 + r2 = -25 + 49 Reorder the terms: 49 + 14r + r2 = -25 + 49 Combine like terms: -25 + 49 = 24 49 + 14r + r2 = 24 Factor a perfect square on the left side: (r + 7)(r + 7) = 24 Calculate the square root of the right side: 4.898979486 Break this problem into two subproblems by setting (r + 7) equal to 4.898979486 and -4.898979486.Subproblem 1
r + 7 = 4.898979486 Simplifying r + 7 = 4.898979486 Reorder the terms: 7 + r = 4.898979486 Solving 7 + r = 4.898979486 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + r = 4.898979486 + -7 Combine like terms: 7 + -7 = 0 0 + r = 4.898979486 + -7 r = 4.898979486 + -7 Combine like terms: 4.898979486 + -7 = -2.101020514 r = -2.101020514 Simplifying r = -2.101020514Subproblem 2
r + 7 = -4.898979486 Simplifying r + 7 = -4.898979486 Reorder the terms: 7 + r = -4.898979486 Solving 7 + r = -4.898979486 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + r = -4.898979486 + -7 Combine like terms: 7 + -7 = 0 0 + r = -4.898979486 + -7 r = -4.898979486 + -7 Combine like terms: -4.898979486 + -7 = -11.898979486 r = -11.898979486 Simplifying r = -11.898979486Solution
The solution to the problem is based on the solutions from the subproblems. r = {-2.101020514, -11.898979486}
