Simplifying -4v2 + 19v + -31 = 0 Reorder the terms: -31 + 19v + -4v2 = 0 Solving -31 + 19v + -4v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 7.75 + -4.75v + v2 = 0 Move the constant term to the right: Add '-7.75' to each side of the equation. 7.75 + -4.75v + -7.75 + v2 = 0 + -7.75 Reorder the terms: 7.75 + -7.75 + -4.75v + v2 = 0 + -7.75 Combine like terms: 7.75 + -7.75 = 0.00 0.00 + -4.75v + v2 = 0 + -7.75 -4.75v + v2 = 0 + -7.75 Combine like terms: 0 + -7.75 = -7.75 -4.75v + v2 = -7.75 The v term is -4.75v. Take half its coefficient (-2.375). Square it (5.640625) and add it to both sides. Add '5.640625' to each side of the equation. -4.75v + 5.640625 + v2 = -7.75 + 5.640625 Reorder the terms: 5.640625 + -4.75v + v2 = -7.75 + 5.640625 Combine like terms: -7.75 + 5.640625 = -2.109375 5.640625 + -4.75v + v2 = -2.109375 Factor a perfect square on the left side: (v + -2.375)(v + -2.375) = -2.109375 Can't calculate square root of the right side. The solution to this equation could not be determined.
