Subproblem 1

Set the factor 'y3' equal to zero and attempt to solve: Simplifying y3 = 0 Solving y3 = 0 Move all terms containing y to the left, all other terms to the right. Simplifying y3 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(4 + -2y + y2)' equal to zero and attempt to solve: Simplifying 4 + -2y + y2 = 0 Solving 4 + -2y + y2 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -2y + -4 + y2 = 0 + -4 Reorder the terms: 4 + -4 + -2y + y2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -2y + y2 = 0 + -4 -2y + y2 = 0 + -4 Combine like terms: 0 + -4 = -4 -2y + y2 = -4 The y term is -2y. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2y + 1 + y2 = -4 + 1 Reorder the terms: 1 + -2y + y2 = -4 + 1 Combine like terms: -4 + 1 = -3 1 + -2y + y2 = -3 Factor a perfect square on the left side: (y + -1)(y + -1) = -3 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.
