Set the factor '(6 + y + 2y2)' equal to zero and attempt to solve: Simplifying 6 + y + 2y2 = 0 Solving 6 + y + 2y2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 3 + 0.5y + y2 = 0 Move the constant term to the right: Add '-3' to each side of the equation. 3 + 0.5y + -3 + y2 = 0 + -3 Reorder the terms: 3 + -3 + 0.5y + y2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 0.5y + y2 = 0 + -3 0.5y + y2 = 0 + -3 Combine like terms: 0 + -3 = -3 0.5y + y2 = -3 The y term is y. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.5y + 0.25 + y2 = -3 + 0.25 Reorder the terms: 0.25 + 0.5y + y2 = -3 + 0.25 Combine like terms: -3 + 0.25 = -2.75 0.25 + 0.5y + y2 = -2.75 Factor a perfect square on the left side: (y + 0.5)(y + 0.5) = -2.75 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
