Simplifying 6u2 + -7u + 3 = 0 Reorder the terms: 3 + -7u + 6u2 = 0 Solving 3 + -7u + 6u2 = 0 Solving for variable 'u'. Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. 0.5 + -1.166666667u + u2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -1.166666667u + -0.5 + u2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -1.166666667u + u2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -1.166666667u + u2 = 0 + -0.5 -1.166666667u + u2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -1.166666667u + u2 = -0.5 The u term is -1.166666667u. Take half its coefficient (-0.5833333335). Square it (0.3402777780) and add it to both sides. Add '0.3402777780' to each side of the equation. -1.166666667u + 0.3402777780 + u2 = -0.5 + 0.3402777780 Reorder the terms: 0.3402777780 + -1.166666667u + u2 = -0.5 + 0.3402777780 Combine like terms: -0.5 + 0.3402777780 = -0.159722222 0.3402777780 + -1.166666667u + u2 = -0.159722222 Factor a perfect square on the left side: (u + -0.5833333335)(u + -0.5833333335) = -0.159722222 Can't calculate square root of the right side. The solution to this equation could not be determined.
