Simplifying v2 + -5v + 12 = 0 Reorder the terms: 12 + -5v + v2 = 0 Solving 12 + -5v + v2 = 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '-12' to each side of the equation. 12 + -5v + -12 + v2 = 0 + -12 Reorder the terms: 12 + -12 + -5v + v2 = 0 + -12 Combine like terms: 12 + -12 = 0 0 + -5v + v2 = 0 + -12 -5v + v2 = 0 + -12 Combine like terms: 0 + -12 = -12 -5v + v2 = -12 The v term is -5v. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5v + 6.25 + v2 = -12 + 6.25 Reorder the terms: 6.25 + -5v + v2 = -12 + 6.25 Combine like terms: -12 + 6.25 = -5.75 6.25 + -5v + v2 = -5.75 Factor a perfect square on the left side: (v + -2.5)(v + -2.5) = -5.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
