Subproblem 1

Set the factor '(69 + -9x + -10x2)' equal to zero and attempt to solve: Simplifying 69 + -9x + -10x2 = 0 Solving 69 + -9x + -10x2 = 0 Begin completing the square. Divide all terms by -10 the coefficient of the squared term: Divide each side by '-10'. -6.9 + 0.9x + x2 = 0.0 Move the constant term to the right: Add '6.9' to each side of the equation. -6.9 + 0.9x + 6.9 + x2 = 0.0 + 6.9 Reorder the terms: -6.9 + 6.9 + 0.9x + x2 = 0.0 + 6.9 Combine like terms: -6.9 + 6.9 = 0.0 0.0 + 0.9x + x2 = 0.0 + 6.9 0.9x + x2 = 0.0 + 6.9 Combine like terms: 0.0 + 6.9 = 6.9 0.9x + x2 = 6.9 The x term is 0.9x. Take half its coefficient (0.45). Square it (0.2025) and add it to both sides. Add '0.2025' to each side of the equation. 0.9x + 0.2025 + x2 = 6.9 + 0.2025 Reorder the terms: 0.2025 + 0.9x + x2 = 6.9 + 0.2025 Combine like terms: 6.9 + 0.2025 = 7.1025 0.2025 + 0.9x + x2 = 7.1025 Factor a perfect square on the left side: (x + 0.45)(x + 0.45) = 7.1025 Calculate the square root of the right side: 2.665051594 Break this problem into two subproblems by setting (x + 0.45) equal to 2.665051594 and -2.665051594.
