Subproblem 1

Set the factor '(-16 + -3x + x2)' equal to zero and attempt to solve: Simplifying -16 + -3x + x2 = 0 Solving -16 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '16' to each side of the equation. -16 + -3x + 16 + x2 = 0 + 16 Reorder the terms: -16 + 16 + -3x + x2 = 0 + 16 Combine like terms: -16 + 16 = 0 0 + -3x + x2 = 0 + 16 -3x + x2 = 0 + 16 Combine like terms: 0 + 16 = 16 -3x + x2 = 16 The x term is -3x. 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. -3x + 2.25 + x2 = 16 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 16 + 2.25 Combine like terms: 16 + 2.25 = 18.25 2.25 + -3x + x2 = 18.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 18.25 Calculate the square root of the right side: 4.272001873 Break this problem into two subproblems by setting (x + -1.5) equal to 4.272001873 and -4.272001873.

Subproblem 1

x + -1.5 = 4.272001873 Simplifying x + -1.5 = 4.272001873 Reorder the terms: -1.5 + x = 4.272001873 Solving -1.5 + x = 4.272001873 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 4.272001873 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 4.272001873 + 1.5 x = 4.272001873 + 1.5 Combine like terms: 4.272001873 + 1.5 = 5.772001873 x = 5.772001873 Simplifying x = 5.772001873

Subproblem 2

x + -1.5 = -4.272001873 Simplifying x + -1.5 = -4.272001873 Reorder the terms: -1.5 + x = -4.272001873 Solving -1.5 + x = -4.272001873 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -4.272001873 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -4.272001873 + 1.5 x = -4.272001873 + 1.5 Combine like terms: -4.272001873 + 1.5 = -2.772001873 x = -2.772001873 Simplifying x = -2.772001873
