Subproblem 1

Set the factor 'y' equal to zero and attempt to solve: Simplifying y = 0 Solving y = 0 Move all terms containing y to the left, all other terms to the right. Simplifying y = 0

Subproblem 2

Set the factor '(-2 + -3y + y2)' equal to zero and attempt to solve: Simplifying -2 + -3y + y2 = 0 Solving -2 + -3y + y2 = 0 Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + -3y + 2 + y2 = 0 + 2 Reorder the terms: -2 + 2 + -3y + y2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -3y + y2 = 0 + 2 -3y + y2 = 0 + 2 Combine like terms: 0 + 2 = 2 -3y + y2 = 2 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 = 2 + 2.25 Reorder the terms: 2.25 + -3y + y2 = 2 + 2.25 Combine like terms: 2 + 2.25 = 4.25 2.25 + -3y + y2 = 4.25 Factor a perfect square on the left side: (y + -1.5)(y + -1.5) = 4.25 Calculate the square root of the right side: 2.061552813 Break this problem into two subproblems by setting (y + -1.5) equal to 2.061552813 and -2.061552813.

Subproblem 1

y + -1.5 = 2.061552813 Simplifying y + -1.5 = 2.061552813 Reorder the terms: -1.5 + y = 2.061552813 Solving -1.5 + y = 2.061552813 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + y = 2.061552813 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + y = 2.061552813 + 1.5 y = 2.061552813 + 1.5 Combine like terms: 2.061552813 + 1.5 = 3.561552813 y = 3.561552813 Simplifying y = 3.561552813

Subproblem 2

y + -1.5 = -2.061552813 Simplifying y + -1.5 = -2.061552813 Reorder the terms: -1.5 + y = -2.061552813 Solving -1.5 + y = -2.061552813 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + y = -2.061552813 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + y = -2.061552813 + 1.5 y = -2.061552813 + 1.5 Combine like terms: -2.061552813 + 1.5 = -0.561552813 y = -0.561552813 Simplifying y = -0.561552813
