Subproblem 1

Set the factor '(3 + -5x + x2)' equal to zero and attempt to solve: Simplifying 3 + -5x + x2 = 0 Solving 3 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + -5x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + -5x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -5x + x2 = 0 + -3 -5x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 -5x + x2 = -3 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -3 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -3 + 6.25 Combine like terms: -3 + 6.25 = 3.25 6.25 + -5x + x2 = 3.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (x + -2.5) equal to 1.802775638 and -1.802775638.
