Simplifying v^{2}+ -4v + 16 = 0 Reorder the terms: 16 + -4v + v^{2}= 0 Solving 16 + -4v + v^{2}= 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -4v + -16 + v^{2}= 0 + -16 Reorder the terms: 16 + -16 + -4v + v^{2}= 0 + -16 Combine like terms: 16 + -16 = 0 0 + -4v + v^{2}= 0 + -16 -4v + v^{2}= 0 + -16 Combine like terms: 0 + -16 = -16 -4v + v^{2}= -16 The v term is -4v. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4v + 4 + v^{2}= -16 + 4 Reorder the terms: 4 + -4v + v^{2}= -16 + 4 Combine like terms: -16 + 4 = -12 4 + -4v + v^{2}= -12 Factor a perfect square on the left side: (v + -2)(v + -2) = -12 Can't calculate square root of the right side. The solution to this equation could not be determined.
