Subproblem 1

Set the factor '(-3 + -6y + 2y2)' equal to zero and attempt to solve: Simplifying -3 + -6y + 2y2 = 0 Solving -3 + -6y + 2y2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1.5 + -3y + y2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -3y + 1.5 + y2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + -3y + y2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -3y + y2 = 0 + 1.5 -3y + y2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 -3y + y2 = 1.5 The y term is -3y. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3y + 2.25 + y2 = 1.5 + 2.25 Reorder the terms: 2.25 + -3y + y2 = 1.5 + 2.25 Combine like terms: 1.5 + 2.25 = 3.75 2.25 + -3y + y2 = 3.75 Factor a perfect square on the left side: (y + -1.5)(y + -1.5) = 3.75 Calculate the square root of the right side: 1.936491673 Break this problem into two subproblems by setting (y + -1.5) equal to 1.936491673 and -1.936491673.
