Simplifying n2 + -7n + 2 = 0 Reorder the terms: 2 + -7n + n2 = 0 Solving 2 + -7n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + -7n + -2 + n2 = 0 + -2 Reorder the terms: 2 + -2 + -7n + n2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -7n + n2 = 0 + -2 -7n + n2 = 0 + -2 Combine like terms: 0 + -2 = -2 -7n + n2 = -2 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 = -2 + 12.25 Reorder the terms: 12.25 + -7n + n2 = -2 + 12.25 Combine like terms: -2 + 12.25 = 10.25 12.25 + -7n + n2 = 10.25 Factor a perfect square on the left side: (n + -3.5)(n + -3.5) = 10.25 Calculate the square root of the right side: 3.201562119 Break this problem into two subproblems by setting (n + -3.5) equal to 3.201562119 and -3.201562119.Subproblem 1
n + -3.5 = 3.201562119 Simplifying n + -3.5 = 3.201562119 Reorder the terms: -3.5 + n = 3.201562119 Solving -3.5 + n = 3.201562119 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 = 3.201562119 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + n = 3.201562119 + 3.5 n = 3.201562119 + 3.5 Combine like terms: 3.201562119 + 3.5 = 6.701562119 n = 6.701562119 Simplifying n = 6.701562119Subproblem 2
n + -3.5 = -3.201562119 Simplifying n + -3.5 = -3.201562119 Reorder the terms: -3.5 + n = -3.201562119 Solving -3.5 + n = -3.201562119 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 = -3.201562119 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + n = -3.201562119 + 3.5 n = -3.201562119 + 3.5 Combine like terms: -3.201562119 + 3.5 = 0.298437881 n = 0.298437881 Simplifying n = 0.298437881Solution
The solution to the problem is based on the solutions from the subproblems. n = {6.701562119, 0.298437881}
