Simplifying 2x2 + -52x + 57 = 0 Reorder the terms: 57 + -52x + 2x2 = 0 Solving 57 + -52x + 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'. 28.5 + -26x + x2 = 0 Move the constant term to the right: Add '-28.5' to each side of the equation. 28.5 + -26x + -28.5 + x2 = 0 + -28.5 Reorder the terms: 28.5 + -28.5 + -26x + x2 = 0 + -28.5 Combine like terms: 28.5 + -28.5 = 0.0 0.0 + -26x + x2 = 0 + -28.5 -26x + x2 = 0 + -28.5 Combine like terms: 0 + -28.5 = -28.5 -26x + x2 = -28.5 The x term is -26x. Take half its coefficient (-13). Square it (169) and add it to both sides. Add '169' to each side of the equation. -26x + 169 + x2 = -28.5 + 169 Reorder the terms: 169 + -26x + x2 = -28.5 + 169 Combine like terms: -28.5 + 169 = 140.5 169 + -26x + x2 = 140.5 Factor a perfect square on the left side: (x + -13)(x + -13) = 140.5 Calculate the square root of the right side: 11.853269591 Break this problem into two subproblems by setting (x + -13) equal to 11.853269591 and -11.853269591.Subproblem 1
x + -13 = 11.853269591 Simplifying x + -13 = 11.853269591 Reorder the terms: -13 + x = 11.853269591 Solving -13 + x = 11.853269591 Solving for variable 'x'.
