Subproblem 1

Set the factor '(2 + -9x + 5x2)' equal to zero and attempt to solve: Simplifying 2 + -9x + 5x2 = 0 Solving 2 + -9x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 0.4 + -1.8x + x2 = 0 Move the constant term to the right: Add '-0.4' to each side of the equation. 0.4 + -1.8x + -0.4 + x2 = 0 + -0.4 Reorder the terms: 0.4 + -0.4 + -1.8x + x2 = 0 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + -1.8x + x2 = 0 + -0.4 -1.8x + x2 = 0 + -0.4 Combine like terms: 0 + -0.4 = -0.4 -1.8x + x2 = -0.4 The x term is -1.8x. Take half its coefficient (-0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. -1.8x + 0.81 + x2 = -0.4 + 0.81 Reorder the terms: 0.81 + -1.8x + x2 = -0.4 + 0.81 Combine like terms: -0.4 + 0.81 = 0.41 0.81 + -1.8x + x2 = 0.41 Factor a perfect square on the left side: (x + -0.9)(x + -0.9) = 0.41 Calculate the square root of the right side: 0.640312424 Break this problem into two subproblems by setting (x + -0.9) equal to 0.640312424 and -0.640312424.
