Simplifying 25(2) + 81 = x2 + -14x + 49 Multiply 25 * 2 50 + 81 = x2 + -14x + 49 Combine like terms: 50 + 81 = 131 131 = x2 + -14x + 49 Reorder the terms: 131 = 49 + -14x + x2 Solving 131 = 49 + -14x + x2 Solving for variable 'x'. Combine like terms: 131 + -49 = 82 82 + 14x + -1x2 = 49 + -14x + x2 + -49 + 14x + -1x2 Reorder the terms: 82 + 14x + -1x2 = 49 + -49 + -14x + 14x + x2 + -1x2 Combine like terms: 49 + -49 = 0 82 + 14x + -1x2 = 0 + -14x + 14x + x2 + -1x2 82 + 14x + -1x2 = -14x + 14x + x2 + -1x2 Combine like terms: -14x + 14x = 0 82 + 14x + -1x2 = 0 + x2 + -1x2 82 + 14x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 82 + 14x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -82 + -14x + x2 = 0 Move the constant term to the right: Add '82' to each side of the equation. -82 + -14x + 82 + x2 = 0 + 82 Reorder the terms: -82 + 82 + -14x + x2 = 0 + 82 Combine like terms: -82 + 82 = 0 0 + -14x + x2 = 0 + 82 -14x + x2 = 0 + 82 Combine like terms: 0 + 82 = 82 -14x + x2 = 82 The x term is -14x. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14x + 49 + x2 = 82 + 49 Reorder the terms: 49 + -14x + x2 = 82 + 49 Combine like terms: 82 + 49 = 131 49 + -14x + x2 = 131 Factor a perfect square on the left side: (x + -7)(x + -7) = 131 Calculate the square root of the right side: 11.445523142 Break this problem into two subproblems by setting (x + -7) equal to 11.445523142 and -11.445523142.Subproblem 1
x + -7 = 11.445523142 Simplifying x + -7 = 11.445523142 Reorder the terms: -7 + x = 11.445523142 Solving -7 + x = 11.445523142 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x = 11.445523142 + 7 Combine like terms: -7 + 7 = 0 0 + x = 11.445523142 + 7 x = 11.445523142 + 7 Combine like terms: 11.445523142 + 7 = 18.445523142 x = 18.445523142 Simplifying x = 18.445523142Subproblem 2
x + -7 = -11.445523142 Simplifying x + -7 = -11.445523142 Reorder the terms: -7 + x = -11.445523142 Solving -7 + x = -11.445523142 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x = -11.445523142 + 7 Combine like terms: -7 + 7 = 0 0 + x = -11.445523142 + 7 x = -11.445523142 + 7 Combine like terms: -11.445523142 + 7 = -4.445523142 x = -4.445523142 Simplifying x = -4.445523142Solution
