Simplifying -1(n + 8) * n = -8n + 2(4n + -4) Reorder the terms: -1(8 + n) * n = -8n + 2(4n + -4) Reorder the terms for easier multiplication: -1n(8 + n) = -8n + 2(4n + -4) (8 * -1n + n * -1n) = -8n + 2(4n + -4) (-8n + -1n2) = -8n + 2(4n + -4) Reorder the terms: -8n + -1n2 = -8n + 2(-4 + 4n) -8n + -1n2 = -8n + (-4 * 2 + 4n * 2) -8n + -1n2 = -8n + (-8 + 8n) Reorder the terms: -8n + -1n2 = -8 + -8n + 8n Combine like terms: -8n + 8n = 0 -8n + -1n2 = -8 + 0 -8n + -1n2 = -8 Solving -8n + -1n2 = -8 Solving for variable 'n'. Reorder the terms: 8 + -8n + -1n2 = -8 + 8 Combine like terms: -8 + 8 = 0 8 + -8n + -1n2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -8 + 8n + n2 = 0 Move the constant term to the right: Add '8' to each side of the equation. -8 + 8n + 8 + n2 = 0 + 8 Reorder the terms: -8 + 8 + 8n + n2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + 8n + n2 = 0 + 8 8n + n2 = 0 + 8 Combine like terms: 0 + 8 = 8 8n + n2 = 8 The n term is 8n. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8n + 16 + n2 = 8 + 16 Reorder the terms: 16 + 8n + n2 = 8 + 16 Combine like terms: 8 + 16 = 24 16 + 8n + n2 = 24 Factor a perfect square on the left side: (n + 4)(n + 4) = 24 Calculate the square root of the right side: 4.898979486 Break this problem into two subproblems by setting (n + 4) equal to 4.898979486 and -4.898979486.Subproblem 1
n + 4 = 4.898979486 Simplifying n + 4 = 4.898979486 Reorder the terms: 4 + n = 4.898979486 Solving 4 + n = 4.898979486 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + n = 4.898979486 + -4 Combine like terms: 4 + -4 = 0 0 + n = 4.898979486 + -4 n = 4.898979486 + -4 Combine like terms: 4.898979486 + -4 = 0.898979486 n = 0.898979486 Simplifying n = 0.898979486Subproblem 2
n + 4 = -4.898979486 Simplifying n + 4 = -4.898979486 Reorder the terms: 4 + n = -4.898979486 Solving 4 + n = -4.898979486 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + n = -4.898979486 + -4 Combine like terms: 4 + -4 = 0 0 + n = -4.898979486 + -4 n = -4.898979486 + -4 Combine like terms: -4.898979486 + -4 = -8.898979486 n = -8.898979486 Simplifying n = -8.898979486Solution
