Simplifying -7v2 + v + -4 = 0 Reorder the terms: -4 + v + -7v2 = 0 Solving -4 + v + -7v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by -7 the coefficient of the squared term: Divide each side by '-7'. 0.5714285714 + -0.1428571429v + v2 = 0 Move the constant term to the right: Add '-0.5714285714' to each side of the equation. 0.5714285714 + -0.1428571429v + -0.5714285714 + v2 = 0 + -0.5714285714 Reorder the terms: 0.5714285714 + -0.5714285714 + -0.1428571429v + v2 = 0 + -0.5714285714 Combine like terms: 0.5714285714 + -0.5714285714 = 0.0000000000 0.0000000000 + -0.1428571429v + v2 = 0 + -0.5714285714 -0.1428571429v + v2 = 0 + -0.5714285714 Combine like terms: 0 + -0.5714285714 = -0.5714285714 -0.1428571429v + v2 = -0.5714285714 The v term is v. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -0.1428571429v + 0.25 + v2 = -0.5714285714 + 0.25 Reorder the terms: 0.25 + -0.1428571429v + v2 = -0.5714285714 + 0.25 Combine like terms: -0.5714285714 + 0.25 = -0.3214285714 0.25 + -0.1428571429v + v2 = -0.3214285714 Factor a perfect square on the left side: (v + 0.5)(v + 0.5) = -0.3214285714 Can't calculate square root of the right side. The solution to this equation could not be determined.
