Subproblem 1

Set the factor '(-4 + -3b + 6b2)' equal to zero and attempt to solve: Simplifying -4 + -3b + 6b2 = 0 Solving -4 + -3b + 6b2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. -0.6666666667 + -0.5b + b2 = 0 Move the constant term to the right: Add '0.6666666667' to each side of the equation. -0.6666666667 + -0.5b + 0.6666666667 + b2 = 0 + 0.6666666667 Reorder the terms: -0.6666666667 + 0.6666666667 + -0.5b + b2 = 0 + 0.6666666667 Combine like terms: -0.6666666667 + 0.6666666667 = 0.0000000000 0.0000000000 + -0.5b + b2 = 0 + 0.6666666667 -0.5b + b2 = 0 + 0.6666666667 Combine like terms: 0 + 0.6666666667 = 0.6666666667 -0.5b + b2 = 0.6666666667 The b term is -0.5b. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5b + 0.0625 + b2 = 0.6666666667 + 0.0625 Reorder the terms: 0.0625 + -0.5b + b2 = 0.6666666667 + 0.0625 Combine like terms: 0.6666666667 + 0.0625 = 0.7291666667 0.0625 + -0.5b + b2 = 0.7291666667 Factor a perfect square on the left side: (b + -0.25)(b + -0.25) = 0.7291666667 Calculate the square root of the right side: 0.853912564 Break this problem into two subproblems by setting (b + -0.25) equal to 0.853912564 and -0.853912564.

Subproblem 1

b + -0.25 = 0.853912564 Simplifying b + -0.25 = 0.853912564 Reorder the terms: -0.25 + b = 0.853912564 Solving -0.25 + b = 0.853912564 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + b = 0.853912564 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + b = 0.853912564 + 0.25 b = 0.853912564 + 0.25 Combine like terms: 0.853912564 + 0.25 = 1.103912564 b = 1.103912564 Simplifying b = 1.103912564

Subproblem 2

b + -0.25 = -0.853912564 Simplifying b + -0.25 = -0.853912564 Reorder the terms: -0.25 + b = -0.853912564 Solving -0.25 + b = -0.853912564 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + b = -0.853912564 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + b = -0.853912564 + 0.25 b = -0.853912564 + 0.25 Combine like terms: -0.853912564 + 0.25 = -0.603912564 b = -0.603912564 Simplifying b = -0.603912564
