Simplifying n2 + 2n + -0.806 = 0 Reorder the terms: -0.806 + 2n + n2 = 0 Solving -0.806 + 2n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '0.806' to each side of the equation. -0.806 + 2n + 0.806 + n2 = 0 + 0.806 Reorder the terms: -0.806 + 0.806 + 2n + n2 = 0 + 0.806 Combine like terms: -0.806 + 0.806 = 0.000 0.000 + 2n + n2 = 0 + 0.806 2n + n2 = 0 + 0.806 Combine like terms: 0 + 0.806 = 0.806 2n + n2 = 0.806 The n term is 2n. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2n + 1 + n2 = 0.806 + 1 Reorder the terms: 1 + 2n + n2 = 0.806 + 1 Combine like terms: 0.806 + 1 = 1.806 1 + 2n + n2 = 1.806 Factor a perfect square on the left side: (n + 1)(n + 1) = 1.806 Calculate the square root of the right side: 1.343874994 Break this problem into two subproblems by setting (n + 1) equal to 1.343874994 and -1.343874994.Subproblem 1
n + 1 = 1.343874994 Simplifying n + 1 = 1.343874994 Reorder the terms: 1 + n = 1.343874994 Solving 1 + n = 1.343874994 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + n = 1.343874994 + -1 Combine like terms: 1 + -1 = 0 0 + n = 1.343874994 + -1 n = 1.343874994 + -1 Combine like terms: 1.343874994 + -1 = 0.343874994 n = 0.343874994 Simplifying n = 0.343874994Subproblem 2
n + 1 = -1.343874994 Simplifying n + 1 = -1.343874994 Reorder the terms: 1 + n = -1.343874994 Solving 1 + n = -1.343874994 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + n = -1.343874994 + -1 Combine like terms: 1 + -1 = 0 0 + n = -1.343874994 + -1 n = -1.343874994 + -1 Combine like terms: -1.343874994 + -1 = -2.343874994 n = -2.343874994 Simplifying n = -2.343874994Solution
The solution to the problem is based on the solutions from the subproblems. n = {0.343874994, -2.343874994}
