Simplifying 2v2 + 3v + 14 = 0 Reorder the terms: 14 + 3v + 2v2 = 0 Solving 14 + 3v + 2v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 7 + 1.5v + v2 = 0 Move the constant term to the right: Add '-7' to each side of the equation. 7 + 1.5v + -7 + v2 = 0 + -7 Reorder the terms: 7 + -7 + 1.5v + v2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 1.5v + v2 = 0 + -7 1.5v + v2 = 0 + -7 Combine like terms: 0 + -7 = -7 1.5v + v2 = -7 The v term is 1.5v. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5v + 0.5625 + v2 = -7 + 0.5625 Reorder the terms: 0.5625 + 1.5v + v2 = -7 + 0.5625 Combine like terms: -7 + 0.5625 = -6.4375 0.5625 + 1.5v + v2 = -6.4375 Factor a perfect square on the left side: (v + 0.75)(v + 0.75) = -6.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
