Subproblem 1

Set the factor '(4 + -27x + 3x2)' equal to zero and attempt to solve: Simplifying 4 + -27x + 3x2 = 0 Solving 4 + -27x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 1.333333333 + -9x + x2 = 0 Move the constant term to the right: Add '-1.333333333' to each side of the equation. 1.333333333 + -9x + -1.333333333 + x2 = 0 + -1.333333333 Reorder the terms: 1.333333333 + -1.333333333 + -9x + x2 = 0 + -1.333333333 Combine like terms: 1.333333333 + -1.333333333 = 0.000000000 0.000000000 + -9x + x2 = 0 + -1.333333333 -9x + x2 = 0 + -1.333333333 Combine like terms: 0 + -1.333333333 = -1.333333333 -9x + x2 = -1.333333333 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = -1.333333333 + 20.25 Reorder the terms: 20.25 + -9x + x2 = -1.333333333 + 20.25 Combine like terms: -1.333333333 + 20.25 = 18.916666667 20.25 + -9x + x2 = 18.916666667 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 18.916666667 Calculate the square root of the right side: 4.34932945 Break this problem into two subproblems by setting (x + -4.5) equal to 4.34932945 and -4.34932945.

Subproblem 1

x + -4.5 = 4.34932945 Simplifying x + -4.5 = 4.34932945 Reorder the terms: -4.5 + x = 4.34932945 Solving -4.5 + x = 4.34932945 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = 4.34932945 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 4.34932945 + 4.5 x = 4.34932945 + 4.5 Combine like terms: 4.34932945 + 4.5 = 8.84932945 x = 8.84932945 Simplifying x = 8.84932945

Subproblem 2

x + -4.5 = -4.34932945 Simplifying x + -4.5 = -4.34932945 Reorder the terms: -4.5 + x = -4.34932945 Solving -4.5 + x = -4.34932945 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = -4.34932945 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = -4.34932945 + 4.5 x = -4.34932945 + 4.5 Combine like terms: -4.34932945 + 4.5 = 0.15067055 x = 0.15067055 Simplifying x = 0.15067055
