Simplifying (9n2 + 6n) + -1(-7n2 + -4n + 5) = 0 Reorder the terms: (6n + 9n2) + -1(-7n2 + -4n + 5) = 0 Remove parenthesis around (6n + 9n2) 6n + 9n2 + -1(-7n2 + -4n + 5) = 0 Reorder the terms: 6n + 9n2 + -1(5 + -4n + -7n2) = 0 6n + 9n2 + (5 * -1 + -4n * -1 + -7n2 * -1) = 0 6n + 9n2 + (-5 + 4n + 7n2) = 0 Reorder the terms: -5 + 6n + 4n + 9n2 + 7n2 = 0 Combine like terms: 6n + 4n = 10n -5 + 10n + 9n2 + 7n2 = 0 Combine like terms: 9n2 + 7n2 = 16n2 -5 + 10n + 16n2 = 0 Solving -5 + 10n + 16n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -0.3125 + 0.625n + n2 = 0 Move the constant term to the right: Add '0.3125' to each side of the equation. -0.3125 + 0.625n + 0.3125 + n2 = 0 + 0.3125 Reorder the terms: -0.3125 + 0.3125 + 0.625n + n2 = 0 + 0.3125 Combine like terms: -0.3125 + 0.3125 = 0.0000 0.0000 + 0.625n + n2 = 0 + 0.3125 0.625n + n2 = 0 + 0.3125 Combine like terms: 0 + 0.3125 = 0.3125 0.625n + n2 = 0.3125 The n term is 0.625n. Take half its coefficient (0.3125). Square it (0.09765625) and add it to both sides. Add '0.09765625' to each side of the equation. 0.625n + 0.09765625 + n2 = 0.3125 + 0.09765625 Reorder the terms: 0.09765625 + 0.625n + n2 = 0.3125 + 0.09765625 Combine like terms: 0.3125 + 0.09765625 = 0.41015625 0.09765625 + 0.625n + n2 = 0.41015625 Factor a perfect square on the left side: (n + 0.3125)(n + 0.3125) = 0.41015625 Calculate the square root of the right side: 0.640434423 Break this problem into two subproblems by setting (n + 0.3125) equal to 0.640434423 and -0.640434423.Subproblem 1
n + 0.3125 = 0.640434423 Simplifying n + 0.3125 = 0.640434423 Reorder the terms: 0.3125 + n = 0.640434423 Solving 0.3125 + n = 0.640434423 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.3125' to each side of the equation. 0.3125 + -0.3125 + n = 0.640434423 + -0.3125 Combine like terms: 0.3125 + -0.3125 = 0.0000 0.0000 + n = 0.640434423 + -0.3125 n = 0.640434423 + -0.3125 Combine like terms: 0.640434423 + -0.3125 = 0.327934423 n = 0.327934423 Simplifying n = 0.327934423Subproblem 2
n + 0.3125 = -0.640434423 Simplifying n + 0.3125 = -0.640434423 Reorder the terms: 0.3125 + n = -0.640434423 Solving 0.3125 + n = -0.640434423 Solving for variable 'n'.
