Simplifying 5n2 + 12n = -3 Reorder the terms: 12n + 5n2 = -3 Solving 12n + 5n2 = -3 Solving for variable 'n'. Reorder the terms: 3 + 12n + 5n2 = -3 + 3 Combine like terms: -3 + 3 = 0 3 + 12n + 5n2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 0.6 + 2.4n + n2 = 0 Move the constant term to the right: Add '-0.6' to each side of the equation. 0.6 + 2.4n + -0.6 + n2 = 0 + -0.6 Reorder the terms: 0.6 + -0.6 + 2.4n + n2 = 0 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + 2.4n + n2 = 0 + -0.6 2.4n + n2 = 0 + -0.6 Combine like terms: 0 + -0.6 = -0.6 2.4n + n2 = -0.6 The n term is 2.4n. Take half its coefficient (1.2). Square it (1.44) and add it to both sides. Add '1.44' to each side of the equation. 2.4n + 1.44 + n2 = -0.6 + 1.44 Reorder the terms: 1.44 + 2.4n + n2 = -0.6 + 1.44 Combine like terms: -0.6 + 1.44 = 0.84 1.44 + 2.4n + n2 = 0.84 Factor a perfect square on the left side: (n + 1.2)(n + 1.2) = 0.84 Calculate the square root of the right side: 0.916515139 Break this problem into two subproblems by setting (n + 1.2) equal to 0.916515139 and -0.916515139.Subproblem 1
n + 1.2 = 0.916515139 Simplifying n + 1.2 = 0.916515139 Reorder the terms: 1.2 + n = 0.916515139 Solving 1.2 + n = 0.916515139 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + n = 0.916515139 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + n = 0.916515139 + -1.2 n = 0.916515139 + -1.2 Combine like terms: 0.916515139 + -1.2 = -0.283484861 n = -0.283484861 Simplifying n = -0.283484861Subproblem 2
n + 1.2 = -0.916515139 Simplifying n + 1.2 = -0.916515139 Reorder the terms: 1.2 + n = -0.916515139 Solving 1.2 + n = -0.916515139 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + n = -0.916515139 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + n = -0.916515139 + -1.2 n = -0.916515139 + -1.2 Combine like terms: -0.916515139 + -1.2 = -2.116515139 n = -2.116515139 Simplifying n = -2.116515139Solution
The solution to the problem is based on the solutions from the subproblems. n = {-0.283484861, -2.116515139}
