Simplifying k2 + -7k + 16 = 0 Reorder the terms: 16 + -7k + k2 = 0 Solving 16 + -7k + k2 = 0 Solving for variable 'k'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -7k + -16 + k2 = 0 + -16 Reorder the terms: 16 + -16 + -7k + k2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -7k + k2 = 0 + -16 -7k + k2 = 0 + -16 Combine like terms: 0 + -16 = -16 -7k + k2 = -16 The k term is -7k. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7k + 12.25 + k2 = -16 + 12.25 Reorder the terms: 12.25 + -7k + k2 = -16 + 12.25 Combine like terms: -16 + 12.25 = -3.75 12.25 + -7k + k2 = -3.75 Factor a perfect square on the left side: (k + -3.5)(k + -3.5) = -3.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
