Simplifying (2x2) + -9x = 1 Reorder the terms: -9x + (2x2) = 1 Solving -9x + (2x2) = 1 Solving for variable 'x'. Reorder the terms: -1 + -9x + (2x2) = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + -9x + (2x2) = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -0.5 + -4.5x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + -4.5x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + -4.5x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + -4.5x + x2 = 0 + 0.5 -4.5x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 -4.5x + x2 = 0.5 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 = 0.5 + 5.0625 Reorder the terms: 5.0625 + -4.5x + x2 = 0.5 + 5.0625 Combine like terms: 0.5 + 5.0625 = 5.5625 5.0625 + -4.5x + x2 = 5.5625 Factor a perfect square on the left side: ((x) + -2.25)((x) + -2.25) = 5.5625 Calculate the square root of the right side: 2.358495283 Break this problem into two subproblems by setting ((x) + -2.25) equal to 2.358495283 and -2.358495283.Subproblem 1
