Simplifying 7r2 + 14r + -26 = -7 Reorder the terms: -26 + 14r + 7r2 = -7 Solving -26 + 14r + 7r2 = -7 Solving for variable 'r'. Reorder the terms: -26 + 7 + 14r + 7r2 = -7 + 7 Combine like terms: -26 + 7 = -19 -19 + 14r + 7r2 = -7 + 7 Combine like terms: -7 + 7 = 0 -19 + 14r + 7r2 = 0 Begin completing the square. Divide all terms by 7 the coefficient of the squared term: Divide each side by '7'. -2.714285714 + 2r + r2 = 0 Move the constant term to the right: Add '2.714285714' to each side of the equation. -2.714285714 + 2r + 2.714285714 + r2 = 0 + 2.714285714 Reorder the terms: -2.714285714 + 2.714285714 + 2r + r2 = 0 + 2.714285714 Combine like terms: -2.714285714 + 2.714285714 = 0.000000000 0.000000000 + 2r + r2 = 0 + 2.714285714 2r + r2 = 0 + 2.714285714 Combine like terms: 0 + 2.714285714 = 2.714285714 2r + r2 = 2.714285714 The r term is 2r. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2r + 1 + r2 = 2.714285714 + 1 Reorder the terms: 1 + 2r + r2 = 2.714285714 + 1 Combine like terms: 2.714285714 + 1 = 3.714285714 1 + 2r + r2 = 3.714285714 Factor a perfect square on the left side: (r + 1)(r + 1) = 3.714285714 Calculate the square root of the right side: 1.927248223 Break this problem into two subproblems by setting (r + 1) equal to 1.927248223 and -1.927248223.Subproblem 1
r + 1 = 1.927248223 Simplifying r + 1 = 1.927248223 Reorder the terms: 1 + r = 1.927248223 Solving 1 + r = 1.927248223 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + r = 1.927248223 + -1 Combine like terms: 1 + -1 = 0 0 + r = 1.927248223 + -1 r = 1.927248223 + -1 Combine like terms: 1.927248223 + -1 = 0.927248223 r = 0.927248223 Simplifying r = 0.927248223Subproblem 2
r + 1 = -1.927248223 Simplifying r + 1 = -1.927248223 Reorder the terms: 1 + r = -1.927248223 Solving 1 + r = -1.927248223 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + r = -1.927248223 + -1 Combine like terms: 1 + -1 = 0 0 + r = -1.927248223 + -1 r = -1.927248223 + -1 Combine like terms: -1.927248223 + -1 = -2.927248223 r = -2.927248223 Simplifying r = -2.927248223Solution
