Simplifying 2n2 + 5n + -4 = 0 Reorder the terms: -4 + 5n + 2n2 = 0 Solving -4 + 5n + 2n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2 + 2.5n + n2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 2.5n + 2 + n2 = 0 + 2 Reorder the terms: -2 + 2 + 2.5n + n2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 2.5n + n2 = 0 + 2 2.5n + n2 = 0 + 2 Combine like terms: 0 + 2 = 2 2.5n + n2 = 2 The n term is 2.5n. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5n + 1.5625 + n2 = 2 + 1.5625 Reorder the terms: 1.5625 + 2.5n + n2 = 2 + 1.5625 Combine like terms: 2 + 1.5625 = 3.5625 1.5625 + 2.5n + n2 = 3.5625 Factor a perfect square on the left side: (n + 1.25)(n + 1.25) = 3.5625 Calculate the square root of the right side: 1.887458609 Break this problem into two subproblems by setting (n + 1.25) equal to 1.887458609 and -1.887458609.Subproblem 1
n + 1.25 = 1.887458609 Simplifying n + 1.25 = 1.887458609 Reorder the terms: 1.25 + n = 1.887458609 Solving 1.25 + n = 1.887458609 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + n = 1.887458609 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + n = 1.887458609 + -1.25 n = 1.887458609 + -1.25 Combine like terms: 1.887458609 + -1.25 = 0.637458609 n = 0.637458609 Simplifying n = 0.637458609Subproblem 2
n + 1.25 = -1.887458609 Simplifying n + 1.25 = -1.887458609 Reorder the terms: 1.25 + n = -1.887458609 Solving 1.25 + n = -1.887458609 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + n = -1.887458609 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + n = -1.887458609 + -1.25 n = -1.887458609 + -1.25 Combine like terms: -1.887458609 + -1.25 = -3.137458609 n = -3.137458609 Simplifying n = -3.137458609Solution
