Simplifying -0.05x2 + 4.5x + -6.5 = 0 Reorder the terms: -6.5 + 4.5x + -0.05x2 = 0 Solving -6.5 + 4.5x + -0.05x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -0.05 the coefficient of the squared term: Divide each side by '-0.05'. 130 + -90x + x2 = 0 Move the constant term to the right: Add '-130' to each side of the equation. 130 + -90x + -130 + x2 = 0 + -130 Reorder the terms: 130 + -130 + -90x + x2 = 0 + -130 Combine like terms: 130 + -130 = 0 0 + -90x + x2 = 0 + -130 -90x + x2 = 0 + -130 Combine like terms: 0 + -130 = -130 -90x + x2 = -130 The x term is -90x. Take half its coefficient (-45). Square it (2025) and add it to both sides. Add '2025' to each side of the equation. -90x + 2025 + x2 = -130 + 2025 Reorder the terms: 2025 + -90x + x2 = -130 + 2025 Combine like terms: -130 + 2025 = 1895 2025 + -90x + x2 = 1895 Factor a perfect square on the left side: (x + -45)(x + -45) = 1895 Calculate the square root of the right side: 43.531597719 Break this problem into two subproblems by setting (x + -45) equal to 43.531597719 and -43.531597719.Subproblem 1
