Subproblem 1

Set the factor '(-3 + -3x + x2)' equal to zero and attempt to solve: Simplifying -3 + -3x + x2 = 0 Solving -3 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + -3x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + -3x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -3x + x2 = 0 + 3 -3x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 -3x + x2 = 3 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 = 3 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 3 + 2.25 Combine like terms: 3 + 2.25 = 5.25 2.25 + -3x + x2 = 5.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 5.25 Calculate the square root of the right side: 2.291287847 Break this problem into two subproblems by setting (x + -1.5) equal to 2.291287847 and -2.291287847.
