Simplifying 25u2 + -9u + 3 = 0 Reorder the terms: 3 + -9u + 25u2 = 0 Solving 3 + -9u + 25u2 = 0 Solving for variable 'u'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. 0.12 + -0.36u + u2 = 0 Move the constant term to the right: Add '-0.12' to each side of the equation. 0.12 + -0.36u + -0.12 + u2 = 0 + -0.12 Reorder the terms: 0.12 + -0.12 + -0.36u + u2 = 0 + -0.12 Combine like terms: 0.12 + -0.12 = 0.00 0.00 + -0.36u + u2 = 0 + -0.12 -0.36u + u2 = 0 + -0.12 Combine like terms: 0 + -0.12 = -0.12 -0.36u + u2 = -0.12 The u term is -0.36u. Take half its coefficient (-0.18). Square it (0.0324) and add it to both sides. Add '0.0324' to each side of the equation. -0.36u + 0.0324 + u2 = -0.12 + 0.0324 Reorder the terms: 0.0324 + -0.36u + u2 = -0.12 + 0.0324 Combine like terms: -0.12 + 0.0324 = -0.0876 0.0324 + -0.36u + u2 = -0.0876 Factor a perfect square on the left side: (u + -0.18)(u + -0.18) = -0.0876 Can't calculate square root of the right side. The solution to this equation could not be determined.
