Subproblem 1

Set the factor '(3 + -1y + 4y2)' equal to zero and attempt to solve: Simplifying 3 + -1y + 4y2 = 0 Solving 3 + -1y + 4y2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.75 + -0.25y + y2 = 0 Move the constant term to the right: Add '-0.75' to each side of the equation. 0.75 + -0.25y + -0.75 + y2 = 0 + -0.75 Reorder the terms: 0.75 + -0.75 + -0.25y + y2 = 0 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + -0.25y + y2 = 0 + -0.75 -0.25y + y2 = 0 + -0.75 Combine like terms: 0 + -0.75 = -0.75 -0.25y + y2 = -0.75 The y term is -0.25y. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25y + 0.015625 + y2 = -0.75 + 0.015625 Reorder the terms: 0.015625 + -0.25y + y2 = -0.75 + 0.015625 Combine like terms: -0.75 + 0.015625 = -0.734375 0.015625 + -0.25y + y2 = -0.734375 Factor a perfect square on the left side: (y + -0.125)(y + -0.125) = -0.734375 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.
