Simplifying 5n2 + 8n + -20 = 0 Reorder the terms: -20 + 8n + 5n2 = 0 Solving -20 + 8n + 5n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -4 + 1.6n + n2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + 1.6n + 4 + n2 = 0 + 4 Reorder the terms: -4 + 4 + 1.6n + n2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 1.6n + n2 = 0 + 4 1.6n + n2 = 0 + 4 Combine like terms: 0 + 4 = 4 1.6n + n2 = 4 The n term is 1.6n. Take half its coefficient (0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. 1.6n + 0.64 + n2 = 4 + 0.64 Reorder the terms: 0.64 + 1.6n + n2 = 4 + 0.64 Combine like terms: 4 + 0.64 = 4.64 0.64 + 1.6n + n2 = 4.64 Factor a perfect square on the left side: (n + 0.8)(n + 0.8) = 4.64 Calculate the square root of the right side: 2.154065923 Break this problem into two subproblems by setting (n + 0.8) equal to 2.154065923 and -2.154065923.Subproblem 1
n + 0.8 = 2.154065923 Simplifying n + 0.8 = 2.154065923 Reorder the terms: 0.8 + n = 2.154065923 Solving 0.8 + n = 2.154065923 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.8' to each side of the equation. 0.8 + -0.8 + n = 2.154065923 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + n = 2.154065923 + -0.8 n = 2.154065923 + -0.8 Combine like terms: 2.154065923 + -0.8 = 1.354065923 n = 1.354065923 Simplifying n = 1.354065923Subproblem 2
n + 0.8 = -2.154065923 Simplifying n + 0.8 = -2.154065923 Reorder the terms: 0.8 + n = -2.154065923 Solving 0.8 + n = -2.154065923 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.8' to each side of the equation. 0.8 + -0.8 + n = -2.154065923 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + n = -2.154065923 + -0.8 n = -2.154065923 + -0.8 Combine like terms: -2.154065923 + -0.8 = -2.954065923 n = -2.954065923 Simplifying n = -2.954065923Solution
