Simplifying 2x2 + -26x + 69 = 0 Reorder the terms: 69 + -26x + 2x2 = 0 Solving 69 + -26x + 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'. 34.5 + -13x + x2 = 0 Move the constant term to the right: Add '-34.5' to each side of the equation. 34.5 + -13x + -34.5 + x2 = 0 + -34.5 Reorder the terms: 34.5 + -34.5 + -13x + x2 = 0 + -34.5 Combine like terms: 34.5 + -34.5 = 0.0 0.0 + -13x + x2 = 0 + -34.5 -13x + x2 = 0 + -34.5 Combine like terms: 0 + -34.5 = -34.5 -13x + x2 = -34.5 The x term is -13x. Take half its coefficient (-6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. -13x + 42.25 + x2 = -34.5 + 42.25 Reorder the terms: 42.25 + -13x + x2 = -34.5 + 42.25 Combine like terms: -34.5 + 42.25 = 7.75 42.25 + -13x + x2 = 7.75 Factor a perfect square on the left side: (x + -6.5)(x + -6.5) = 7.75 Calculate the square root of the right side: 2.783882181 Break this problem into two subproblems by setting (x + -6.5) equal to 2.783882181 and -2.783882181.Subproblem 1
x + -6.5 = 2.783882181 Simplifying x + -6.5 = 2.783882181 Reorder the terms: -6.5 + x = 2.783882181 Solving -6.5 + x = 2.783882181 Solving for variable 'x'.
