Simplifying 5n2 + -8n + 2 = 0 Reorder the terms: 2 + -8n + 5n2 = 0 Solving 2 + -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'. 0.4 + -1.6n + n2 = 0 Move the constant term to the right: Add '-0.4' to each side of the equation. 0.4 + -1.6n + -0.4 + n2 = 0 + -0.4 Reorder the terms: 0.4 + -0.4 + -1.6n + n2 = 0 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + -1.6n + n2 = 0 + -0.4 -1.6n + n2 = 0 + -0.4 Combine like terms: 0 + -0.4 = -0.4 -1.6n + n2 = -0.4 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 = -0.4 + 0.64 Reorder the terms: 0.64 + -1.6n + n2 = -0.4 + 0.64 Combine like terms: -0.4 + 0.64 = 0.24 0.64 + -1.6n + n2 = 0.24 Factor a perfect square on the left side: (n + -0.8)(n + -0.8) = 0.24 Calculate the square root of the right side: 0.489897949 Break this problem into two subproblems by setting (n + -0.8) equal to 0.489897949 and -0.489897949.Subproblem 1
n + -0.8 = 0.489897949 Simplifying n + -0.8 = 0.489897949 Reorder the terms: -0.8 + n = 0.489897949 Solving -0.8 + n = 0.489897949 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 = 0.489897949 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + n = 0.489897949 + 0.8 n = 0.489897949 + 0.8 Combine like terms: 0.489897949 + 0.8 = 1.289897949 n = 1.289897949 Simplifying n = 1.289897949Subproblem 2
n + -0.8 = -0.489897949 Simplifying n + -0.8 = -0.489897949 Reorder the terms: -0.8 + n = -0.489897949 Solving -0.8 + n = -0.489897949 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 = -0.489897949 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + n = -0.489897949 + 0.8 n = -0.489897949 + 0.8 Combine like terms: -0.489897949 + 0.8 = 0.310102051 n = 0.310102051 Simplifying n = 0.310102051Solution
