Simplifying k2 + -1k + -17 = -25 Reorder the terms: -17 + -1k + k2 = -25 Solving -17 + -1k + k2 = -25 Solving for variable 'k'. Reorder the terms: -17 + 25 + -1k + k2 = -25 + 25 Combine like terms: -17 + 25 = 8 8 + -1k + k2 = -25 + 25 Combine like terms: -25 + 25 = 0 8 + -1k + k2 = 0 Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + -1k + -8 + k2 = 0 + -8 Reorder the terms: 8 + -8 + -1k + k2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -1k + k2 = 0 + -8 -1k + k2 = 0 + -8 Combine like terms: 0 + -8 = -8 -1k + k2 = -8 The k term is -1k. 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. -1k + 0.25 + k2 = -8 + 0.25 Reorder the terms: 0.25 + -1k + k2 = -8 + 0.25 Combine like terms: -8 + 0.25 = -7.75 0.25 + -1k + k2 = -7.75 Factor a perfect square on the left side: (k + -0.5)(k + -0.5) = -7.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
