Simplifying v2 + -3v + 20 = 0 Reorder the terms: 20 + -3v + v2 = 0 Solving 20 + -3v + v2 = 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '-20' to each side of the equation. 20 + -3v + -20 + v2 = 0 + -20 Reorder the terms: 20 + -20 + -3v + v2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -3v + v2 = 0 + -20 -3v + v2 = 0 + -20 Combine like terms: 0 + -20 = -20 -3v + v2 = -20 The v term is -3v. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3v + 2.25 + v2 = -20 + 2.25 Reorder the terms: 2.25 + -3v + v2 = -20 + 2.25 Combine like terms: -20 + 2.25 = -17.75 2.25 + -3v + v2 = -17.75 Factor a perfect square on the left side: (v + -1.5)(v + -1.5) = -17.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
