Simplifying 4n(n + -3) + 7 = 0 Reorder the terms: 4n(-3 + n) + 7 = 0 (-3 * 4n + n * 4n) + 7 = 0 (-12n + 4n2) + 7 = 0 Reorder the terms: 7 + -12n + 4n2 = 0 Solving 7 + -12n + 4n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.75 + -3n + n2 = 0 Move the constant term to the right: Add '-1.75' to each side of the equation. 1.75 + -3n + -1.75 + n2 = 0 + -1.75 Reorder the terms: 1.75 + -1.75 + -3n + n2 = 0 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + -3n + n2 = 0 + -1.75 -3n + n2 = 0 + -1.75 Combine like terms: 0 + -1.75 = -1.75 -3n + n2 = -1.75 The n term is -3n. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3n + 2.25 + n2 = -1.75 + 2.25 Reorder the terms: 2.25 + -3n + n2 = -1.75 + 2.25 Combine like terms: -1.75 + 2.25 = 0.5 2.25 + -3n + n2 = 0.5 Factor a perfect square on the left side: (n + -1.5)(n + -1.5) = 0.5 Calculate the square root of the right side: 0.707106781 Break this problem into two subproblems by setting (n + -1.5) equal to 0.707106781 and -0.707106781.Subproblem 1
n + -1.5 = 0.707106781 Simplifying n + -1.5 = 0.707106781 Reorder the terms: -1.5 + n = 0.707106781 Solving -1.5 + n = 0.707106781 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + n = 0.707106781 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + n = 0.707106781 + 1.5 n = 0.707106781 + 1.5 Combine like terms: 0.707106781 + 1.5 = 2.207106781 n = 2.207106781 Simplifying n = 2.207106781Subproblem 2
n + -1.5 = -0.707106781 Simplifying n + -1.5 = -0.707106781 Reorder the terms: -1.5 + n = -0.707106781 Solving -1.5 + n = -0.707106781 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + n = -0.707106781 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + n = -0.707106781 + 1.5 n = -0.707106781 + 1.5 Combine like terms: -0.707106781 + 1.5 = 0.792893219 n = 0.792893219 Simplifying n = 0.792893219Solution
The solution to the problem is based on the solutions from the subproblems. n = {2.207106781, 0.792893219}
