Simplifying 2x2 + -9x = -3 Reorder the terms: -9x + 2x2 = -3 Solving -9x + 2x2 = -3 Solving for variable 'x'. Reorder the terms: 3 + -9x + 2x2 = -3 + 3 Combine like terms: -3 + 3 = 0 3 + -9x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 1.5 + -4.5x + x2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + -4.5x + -1.5 + x2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + -4.5x + x2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + -4.5x + x2 = 0 + -1.5 -4.5x + x2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 -4.5x + x2 = -1.5 The x term is -4.5x. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5x + 5.0625 + x2 = -1.5 + 5.0625 Reorder the terms: 5.0625 + -4.5x + x2 = -1.5 + 5.0625 Combine like terms: -1.5 + 5.0625 = 3.5625 5.0625 + -4.5x + x2 = 3.5625 Factor a perfect square on the left side: (x + -2.25)(x + -2.25) = 3.5625 Calculate the square root of the right side: 1.887458609 Break this problem into two subproblems by setting (x + -2.25) equal to 1.887458609 and -1.887458609.Subproblem 1
