Subproblem 1

Set the factor '(4 + 3y + -12y2)' equal to zero and attempt to solve: Simplifying 4 + 3y + -12y2 = 0 Solving 4 + 3y + -12y2 = 0 Begin completing the square. Divide all terms by -12 the coefficient of the squared term: Divide each side by '-12'. -0.3333333333 + -0.25y + y2 = 0 Move the constant term to the right: Add '0.3333333333' to each side of the equation. -0.3333333333 + -0.25y + 0.3333333333 + y2 = 0 + 0.3333333333 Reorder the terms: -0.3333333333 + 0.3333333333 + -0.25y + y2 = 0 + 0.3333333333 Combine like terms: -0.3333333333 + 0.3333333333 = 0.0000000000 0.0000000000 + -0.25y + y2 = 0 + 0.3333333333 -0.25y + y2 = 0 + 0.3333333333 Combine like terms: 0 + 0.3333333333 = 0.3333333333 -0.25y + y2 = 0.3333333333 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 = 0.3333333333 + 0.015625 Reorder the terms: 0.015625 + -0.25y + y2 = 0.3333333333 + 0.015625 Combine like terms: 0.3333333333 + 0.015625 = 0.3489583333 0.015625 + -0.25y + y2 = 0.3489583333 Factor a perfect square on the left side: (y + -0.125)(y + -0.125) = 0.3489583333 Calculate the square root of the right side: 0.590726953 Break this problem into two subproblems by setting (y + -0.125) equal to 0.590726953 and -0.590726953.

Subproblem 1

y + -0.125 = 0.590726953 Simplifying y + -0.125 = 0.590726953 Reorder the terms: -0.125 + y = 0.590726953 Solving -0.125 + y = 0.590726953 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + y = 0.590726953 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + y = 0.590726953 + 0.125 y = 0.590726953 + 0.125 Combine like terms: 0.590726953 + 0.125 = 0.715726953 y = 0.715726953 Simplifying y = 0.715726953

Subproblem 2

y + -0.125 = -0.590726953 Simplifying y + -0.125 = -0.590726953 Reorder the terms: -0.125 + y = -0.590726953 Solving -0.125 + y = -0.590726953 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + y = -0.590726953 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + y = -0.590726953 + 0.125 y = -0.590726953 + 0.125 Combine like terms: -0.590726953 + 0.125 = -0.465726953 y = -0.465726953 Simplifying y = -0.465726953
