Simplifying n2 + -4n + -19 = 0 Reorder the terms: -19 + -4n + n2 = 0 Solving -19 + -4n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '19' to each side of the equation. -19 + -4n + 19 + n2 = 0 + 19 Reorder the terms: -19 + 19 + -4n + n2 = 0 + 19 Combine like terms: -19 + 19 = 0 0 + -4n + n2 = 0 + 19 -4n + n2 = 0 + 19 Combine like terms: 0 + 19 = 19 -4n + n2 = 19 The n term is -4n. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4n + 4 + n2 = 19 + 4 Reorder the terms: 4 + -4n + n2 = 19 + 4 Combine like terms: 19 + 4 = 23 4 + -4n + n2 = 23 Factor a perfect square on the left side: (n + -2)(n + -2) = 23 Calculate the square root of the right side: 4.795831523 Break this problem into two subproblems by setting (n + -2) equal to 4.795831523 and -4.795831523.Subproblem 1
n + -2 = 4.795831523 Simplifying n + -2 = 4.795831523 Reorder the terms: -2 + n = 4.795831523 Solving -2 + n = 4.795831523 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + n = 4.795831523 + 2 Combine like terms: -2 + 2 = 0 0 + n = 4.795831523 + 2 n = 4.795831523 + 2 Combine like terms: 4.795831523 + 2 = 6.795831523 n = 6.795831523 Simplifying n = 6.795831523Subproblem 2
n + -2 = -4.795831523 Simplifying n + -2 = -4.795831523 Reorder the terms: -2 + n = -4.795831523 Solving -2 + n = -4.795831523 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + n = -4.795831523 + 2 Combine like terms: -2 + 2 = 0 0 + n = -4.795831523 + 2 n = -4.795831523 + 2 Combine like terms: -4.795831523 + 2 = -2.795831523 n = -2.795831523 Simplifying n = -2.795831523Solution
