Simplifying n2 + -8n + 65 = 9 Reorder the terms: 65 + -8n + n2 = 9 Solving 65 + -8n + n2 = 9 Solving for variable 'n'. Reorder the terms: 65 + -9 + -8n + n2 = 9 + -9 Combine like terms: 65 + -9 = 56 56 + -8n + n2 = 9 + -9 Combine like terms: 9 + -9 = 0 56 + -8n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '-56' to each side of the equation. 56 + -8n + -56 + n2 = 0 + -56 Reorder the terms: 56 + -56 + -8n + n2 = 0 + -56 Combine like terms: 56 + -56 = 0 0 + -8n + n2 = 0 + -56 -8n + n2 = 0 + -56 Combine like terms: 0 + -56 = -56 -8n + n2 = -56 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 = -56 + 16 Reorder the terms: 16 + -8n + n2 = -56 + 16 Combine like terms: -56 + 16 = -40 16 + -8n + n2 = -40 Factor a perfect square on the left side: (n + -4)(n + -4) = -40 Can't calculate square root of the right side. The solution to this equation could not be determined.
