Simplifying 4k2 + -3k + 6 = 3 Reorder the terms: 6 + -3k + 4k2 = 3 Solving 6 + -3k + 4k2 = 3 Solving for variable 'k'. Reorder the terms: 6 + -3 + -3k + 4k2 = 3 + -3 Combine like terms: 6 + -3 = 3 3 + -3k + 4k2 = 3 + -3 Combine like terms: 3 + -3 = 0 3 + -3k + 4k2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.75 + -0.75k + k2 = 0 Move the constant term to the right: Add '-0.75' to each side of the equation. 0.75 + -0.75k + -0.75 + k2 = 0 + -0.75 Reorder the terms: 0.75 + -0.75 + -0.75k + k2 = 0 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + -0.75k + k2 = 0 + -0.75 -0.75k + k2 = 0 + -0.75 Combine like terms: 0 + -0.75 = -0.75 -0.75k + k2 = -0.75 The k term is -0.75k. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75k + 0.140625 + k2 = -0.75 + 0.140625 Reorder the terms: 0.140625 + -0.75k + k2 = -0.75 + 0.140625 Combine like terms: -0.75 + 0.140625 = -0.609375 0.140625 + -0.75k + k2 = -0.609375 Factor a perfect square on the left side: (k + -0.375)(k + -0.375) = -0.609375 Can't calculate square root of the right side. The solution to this equation could not be determined.
