Simplifying 2x2 + -23x + 6 = 0 Reorder the terms: 6 + -23x + 2x2 = 0 Solving 6 + -23x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 3 + -11.5x + x2 = 0 Move the constant term to the right: Add '-3' to each side of the equation. 3 + -11.5x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + -11.5x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -11.5x + x2 = 0 + -3 -11.5x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 -11.5x + x2 = -3 The x term is -11.5x. Take half its coefficient (-5.75). Square it (33.0625) and add it to both sides. Add '33.0625' to each side of the equation. -11.5x + 33.0625 + x2 = -3 + 33.0625 Reorder the terms: 33.0625 + -11.5x + x2 = -3 + 33.0625 Combine like terms: -3 + 33.0625 = 30.0625 33.0625 + -11.5x + x2 = 30.0625 Factor a perfect square on the left side: (x + -5.75)(x + -5.75) = 30.0625 Calculate the square root of the right side: 5.48292805 Break this problem into two subproblems by setting (x + -5.75) equal to 5.48292805 and -5.48292805.Subproblem 1
