Subproblem 1

Set the factor '(7 + -3x + -2x2)' equal to zero and attempt to solve: Simplifying 7 + -3x + -2x2 = 0 Solving 7 + -3x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -3.5 + 1.5x + x2 = 0 Move the constant term to the right: Add '3.5' to each side of the equation. -3.5 + 1.5x + 3.5 + x2 = 0 + 3.5 Reorder the terms: -3.5 + 3.5 + 1.5x + x2 = 0 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + 1.5x + x2 = 0 + 3.5 1.5x + x2 = 0 + 3.5 Combine like terms: 0 + 3.5 = 3.5 1.5x + x2 = 3.5 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 = 3.5 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 3.5 + 0.5625 Combine like terms: 3.5 + 0.5625 = 4.0625 0.5625 + 1.5x + x2 = 4.0625 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 4.0625 Calculate the square root of the right side: 2.015564437 Break this problem into two subproblems by setting (x + 0.75) equal to 2.015564437 and -2.015564437.
