Subproblem 1

Set the factor '(-23 + 3x + 2x2)' equal to zero and attempt to solve: Simplifying -23 + 3x + 2x2 = 0 Solving -23 + 3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -11.5 + 1.5x + x2 = 0 Move the constant term to the right: Add '11.5' to each side of the equation. -11.5 + 1.5x + 11.5 + x2 = 0 + 11.5 Reorder the terms: -11.5 + 11.5 + 1.5x + x2 = 0 + 11.5 Combine like terms: -11.5 + 11.5 = 0.0 0.0 + 1.5x + x2 = 0 + 11.5 1.5x + x2 = 0 + 11.5 Combine like terms: 0 + 11.5 = 11.5 1.5x + x2 = 11.5 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = 11.5 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 11.5 + 0.5625 Combine like terms: 11.5 + 0.5625 = 12.0625 0.5625 + 1.5x + x2 = 12.0625 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 12.0625 Calculate the square root of the right side: 3.473110997 Break this problem into two subproblems by setting (x + 0.75) equal to 3.473110997 and -3.473110997.
