Simplifying 4v2 + -8v + 68 = 0 Reorder the terms: 68 + -8v + 4v2 = 0 Solving 68 + -8v + 4v2 = 0 Solving for variable 'v'. Factor out the Greatest Common Factor (GCF), '4'. 4(17 + -2v + v2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(17 + -2v + v2)' equal to zero and attempt to solve: Simplifying 17 + -2v + v2 = 0 Solving 17 + -2v + v2 = 0 Begin completing the square. Move the constant term to the right: Add '-17' to each side of the equation. 17 + -2v + -17 + v2 = 0 + -17 Reorder the terms: 17 + -17 + -2v + v2 = 0 + -17 Combine like terms: 17 + -17 = 0 0 + -2v + v2 = 0 + -17 -2v + v2 = 0 + -17 Combine like terms: 0 + -17 = -17 -2v + v2 = -17 The v term is -2v. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2v + 1 + v2 = -17 + 1 Reorder the terms: 1 + -2v + v2 = -17 + 1 Combine like terms: -17 + 1 = -16 1 + -2v + v2 = -16 Factor a perfect square on the left side: (v + -1)(v + -1) = -16 Can't calculate square root of the right side.
