Simplifying v2 + 7v + 16 = 0 Reorder the terms: 16 + 7v + v2 = 0 Solving 16 + 7v + v2 = 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + 7v + -16 + v2 = 0 + -16 Reorder the terms: 16 + -16 + 7v + v2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + 7v + v2 = 0 + -16 7v + v2 = 0 + -16 Combine like terms: 0 + -16 = -16 7v + v2 = -16 The v term is 7v. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7v + 12.25 + v2 = -16 + 12.25 Reorder the terms: 12.25 + 7v + v2 = -16 + 12.25 Combine like terms: -16 + 12.25 = -3.75 12.25 + 7v + v2 = -3.75 Factor a perfect square on the left side: (v + 3.5)(v + 3.5) = -3.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
