Simplifying 2n + 29 = n2 + 9 Reorder the terms: 29 + 2n = n2 + 9 Reorder the terms: 29 + 2n = 9 + n2 Solving 29 + 2n = 9 + n2 Solving for variable 'n'. Reorder the terms: 29 + -9 + 2n + -1n2 = 9 + n2 + -9 + -1n2 Combine like terms: 29 + -9 = 20 20 + 2n + -1n2 = 9 + n2 + -9 + -1n2 Reorder the terms: 20 + 2n + -1n2 = 9 + -9 + n2 + -1n2 Combine like terms: 9 + -9 = 0 20 + 2n + -1n2 = 0 + n2 + -1n2 20 + 2n + -1n2 = n2 + -1n2 Combine like terms: n2 + -1n2 = 0 20 + 2n + -1n2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -20 + -2n + n2 = 0 Move the constant term to the right: Add '20' to each side of the equation. -20 + -2n + 20 + n2 = 0 + 20 Reorder the terms: -20 + 20 + -2n + n2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -2n + n2 = 0 + 20 -2n + n2 = 0 + 20 Combine like terms: 0 + 20 = 20 -2n + n2 = 20 The n term is -2n. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2n + 1 + n2 = 20 + 1 Reorder the terms: 1 + -2n + n2 = 20 + 1 Combine like terms: 20 + 1 = 21 1 + -2n + n2 = 21 Factor a perfect square on the left side: (n + -1)(n + -1) = 21 Calculate the square root of the right side: 4.582575695 Break this problem into two subproblems by setting (n + -1) equal to 4.582575695 and -4.582575695.Subproblem 1
n + -1 = 4.582575695 Simplifying n + -1 = 4.582575695 Reorder the terms: -1 + n = 4.582575695 Solving -1 + n = 4.582575695 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + n = 4.582575695 + 1 Combine like terms: -1 + 1 = 0 0 + n = 4.582575695 + 1 n = 4.582575695 + 1 Combine like terms: 4.582575695 + 1 = 5.582575695 n = 5.582575695 Simplifying n = 5.582575695Subproblem 2
n + -1 = -4.582575695 Simplifying n + -1 = -4.582575695 Reorder the terms: -1 + n = -4.582575695 Solving -1 + n = -4.582575695 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + n = -4.582575695 + 1 Combine like terms: -1 + 1 = 0 0 + n = -4.582575695 + 1 n = -4.582575695 + 1 Combine like terms: -4.582575695 + 1 = -3.582575695 n = -3.582575695 Simplifying n = -3.582575695Solution
