Simplifying n2 + -1n + -56 = 1 Reorder the terms: -56 + -1n + n2 = 1 Solving -56 + -1n + n2 = 1 Solving for variable 'n'. Reorder the terms: -56 + -1 + -1n + n2 = 1 + -1 Combine like terms: -56 + -1 = -57 -57 + -1n + n2 = 1 + -1 Combine like terms: 1 + -1 = 0 -57 + -1n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '57' to each side of the equation. -57 + -1n + 57 + n2 = 0 + 57 Reorder the terms: -57 + 57 + -1n + n2 = 0 + 57 Combine like terms: -57 + 57 = 0 0 + -1n + n2 = 0 + 57 -1n + n2 = 0 + 57 Combine like terms: 0 + 57 = 57 -1n + n2 = 57 The n term is -1n. 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. -1n + 0.25 + n2 = 57 + 0.25 Reorder the terms: 0.25 + -1n + n2 = 57 + 0.25 Combine like terms: 57 + 0.25 = 57.25 0.25 + -1n + n2 = 57.25 Factor a perfect square on the left side: (n + -0.5)(n + -0.5) = 57.25 Calculate the square root of the right side: 7.566372975 Break this problem into two subproblems by setting (n + -0.5) equal to 7.566372975 and -7.566372975.Subproblem 1
n + -0.5 = 7.566372975 Simplifying n + -0.5 = 7.566372975 Reorder the terms: -0.5 + n = 7.566372975 Solving -0.5 + n = 7.566372975 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 = 7.566372975 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + n = 7.566372975 + 0.5 n = 7.566372975 + 0.5 Combine like terms: 7.566372975 + 0.5 = 8.066372975 n = 8.066372975 Simplifying n = 8.066372975Subproblem 2
n + -0.5 = -7.566372975 Simplifying n + -0.5 = -7.566372975 Reorder the terms: -0.5 + n = -7.566372975 Solving -0.5 + n = -7.566372975 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 = -7.566372975 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + n = -7.566372975 + 0.5 n = -7.566372975 + 0.5 Combine like terms: -7.566372975 + 0.5 = -7.066372975 n = -7.066372975 Simplifying n = -7.066372975Solution
The solution to the problem is based on the solutions from the subproblems. n = {8.066372975, -7.066372975}
