Simplifying 2n(n + 7) = 15 Reorder the terms: 2n(7 + n) = 15 (7 * 2n + n * 2n) = 15 (14n + 2n2) = 15 Solving 14n + 2n2 = 15 Solving for variable 'n'. Reorder the terms: -15 + 14n + 2n2 = 15 + -15 Combine like terms: 15 + -15 = 0 -15 + 14n + 2n2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -7.5 + 7n + n2 = 0 Move the constant term to the right: Add '7.5' to each side of the equation. -7.5 + 7n + 7.5 + n2 = 0 + 7.5 Reorder the terms: -7.5 + 7.5 + 7n + n2 = 0 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + 7n + n2 = 0 + 7.5 7n + n2 = 0 + 7.5 Combine like terms: 0 + 7.5 = 7.5 7n + n2 = 7.5 The n term is 7n. 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. 7n + 12.25 + n2 = 7.5 + 12.25 Reorder the terms: 12.25 + 7n + n2 = 7.5 + 12.25 Combine like terms: 7.5 + 12.25 = 19.75 12.25 + 7n + n2 = 19.75 Factor a perfect square on the left side: (n + 3.5)(n + 3.5) = 19.75 Calculate the square root of the right side: 4.444097209 Break this problem into two subproblems by setting (n + 3.5) equal to 4.444097209 and -4.444097209.Subproblem 1
n + 3.5 = 4.444097209 Simplifying n + 3.5 = 4.444097209 Reorder the terms: 3.5 + n = 4.444097209 Solving 3.5 + n = 4.444097209 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + n = 4.444097209 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + n = 4.444097209 + -3.5 n = 4.444097209 + -3.5 Combine like terms: 4.444097209 + -3.5 = 0.944097209 n = 0.944097209 Simplifying n = 0.944097209Subproblem 2
n + 3.5 = -4.444097209 Simplifying n + 3.5 = -4.444097209 Reorder the terms: 3.5 + n = -4.444097209 Solving 3.5 + n = -4.444097209 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + n = -4.444097209 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + n = -4.444097209 + -3.5 n = -4.444097209 + -3.5 Combine like terms: -4.444097209 + -3.5 = -7.944097209 n = -7.944097209 Simplifying n = -7.944097209Solution
The solution to the problem is based on the solutions from the subproblems. n = {0.944097209, -7.944097209}
