Simplifying 2y2 + 8y + 31 = 0 Reorder the terms: 31 + 8y + 2y2 = 0 Solving 31 + 8y + 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'. 15.5 + 4y + y2 = 0 Move the constant term to the right: Add '-15.5' to each side of the equation. 15.5 + 4y + -15.5 + y2 = 0 + -15.5 Reorder the terms: 15.5 + -15.5 + 4y + y2 = 0 + -15.5 Combine like terms: 15.5 + -15.5 = 0.0 0.0 + 4y + y2 = 0 + -15.5 4y + y2 = 0 + -15.5 Combine like terms: 0 + -15.5 = -15.5 4y + y2 = -15.5 The y term is 4y. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4y + 4 + y2 = -15.5 + 4 Reorder the terms: 4 + 4y + y2 = -15.5 + 4 Combine like terms: -15.5 + 4 = -11.5 4 + 4y + y2 = -11.5 Factor a perfect square on the left side: (y + 2)(y + 2) = -11.5 Can't calculate square root of the right side. The solution to this equation could not be determined.
