Simplifying 2y2 + -37y + 242 = 0 Reorder the terms: 242 + -37y + 2y2 = 0 Solving 242 + -37y + 2y2 = 0 Solving for variable 'y'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 121 + -18.5y + y2 = 0 Move the constant term to the right: Add '-121' to each side of the equation. 121 + -18.5y + -121 + y2 = 0 + -121 Reorder the terms: 121 + -121 + -18.5y + y2 = 0 + -121 Combine like terms: 121 + -121 = 0 0 + -18.5y + y2 = 0 + -121 -18.5y + y2 = 0 + -121 Combine like terms: 0 + -121 = -121 -18.5y + y2 = -121 The y term is -18.5y. Take half its coefficient (-9.25). Square it (85.5625) and add it to both sides. Add '85.5625' to each side of the equation. -18.5y + 85.5625 + y2 = -121 + 85.5625 Reorder the terms: 85.5625 + -18.5y + y2 = -121 + 85.5625 Combine like terms: -121 + 85.5625 = -35.4375 85.5625 + -18.5y + y2 = -35.4375 Factor a perfect square on the left side: (y + -9.25)(y + -9.25) = -35.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
