Simplifying n2 + -4n + -7 = 0 Reorder the terms: -7 + -4n + n2 = 0 Solving -7 + -4n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '7' to each side of the equation. -7 + -4n + 7 + n2 = 0 + 7 Reorder the terms: -7 + 7 + -4n + n2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -4n + n2 = 0 + 7 -4n + n2 = 0 + 7 Combine like terms: 0 + 7 = 7 -4n + n2 = 7 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 = 7 + 4 Reorder the terms: 4 + -4n + n2 = 7 + 4 Combine like terms: 7 + 4 = 11 4 + -4n + n2 = 11 Factor a perfect square on the left side: (n + -2)(n + -2) = 11 Calculate the square root of the right side: 3.31662479 Break this problem into two subproblems by setting (n + -2) equal to 3.31662479 and -3.31662479.Subproblem 1
n + -2 = 3.31662479 Simplifying n + -2 = 3.31662479 Reorder the terms: -2 + n = 3.31662479 Solving -2 + n = 3.31662479 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 = 3.31662479 + 2 Combine like terms: -2 + 2 = 0 0 + n = 3.31662479 + 2 n = 3.31662479 + 2 Combine like terms: 3.31662479 + 2 = 5.31662479 n = 5.31662479 Simplifying n = 5.31662479Subproblem 2
