Simplifying n2 + n + -150 = 0 Reorder the terms: -150 + n + n2 = 0 Solving -150 + n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '150' to each side of the equation. -150 + n + 150 + n2 = 0 + 150 Reorder the terms: -150 + 150 + n + n2 = 0 + 150 Combine like terms: -150 + 150 = 0 0 + n + n2 = 0 + 150 n + n2 = 0 + 150 Combine like terms: 0 + 150 = 150 n + n2 = 150 The n term is n. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. n + 0.25 + n2 = 150 + 0.25 Reorder the terms: 0.25 + n + n2 = 150 + 0.25 Combine like terms: 150 + 0.25 = 150.25 0.25 + n + n2 = 150.25 Factor a perfect square on the left side: (n + 0.5)(n + 0.5) = 150.25 Calculate the square root of the right side: 12.257650672 Break this problem into two subproblems by setting (n + 0.5) equal to 12.257650672 and -12.257650672.Subproblem 1
n + 0.5 = 12.257650672 Simplifying n + 0.5 = 12.257650672 Reorder the terms: 0.5 + n = 12.257650672 Solving 0.5 + n = 12.257650672 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + n = 12.257650672 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + n = 12.257650672 + -0.5 n = 12.257650672 + -0.5 Combine like terms: 12.257650672 + -0.5 = 11.757650672 n = 11.757650672 Simplifying n = 11.757650672Subproblem 2
n + 0.5 = -12.257650672 Simplifying n + 0.5 = -12.257650672 Reorder the terms: 0.5 + n = -12.257650672 Solving 0.5 + n = -12.257650672 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + n = -12.257650672 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + n = -12.257650672 + -0.5 n = -12.257650672 + -0.5 Combine like terms: -12.257650672 + -0.5 = -12.757650672 n = -12.757650672 Simplifying n = -12.757650672Solution
The solution to the problem is based on the solutions from the subproblems. n = {11.757650672, -12.757650672}
