Simplifying (15 + 20) * 15 = (x + 26) * x Combine like terms: 15 + 20 = 35 (35) * 15 = (x + 26) * x Multiply 35 * 15 525 = (x + 26) * x Reorder the terms: 525 = (26 + x) * x Reorder the terms for easier multiplication: 525 = x(26 + x) 525 = (26 * x + x * x) 525 = (26x + x2) Solving 525 = 26x + x2 Solving for variable 'x'. Reorder the terms: 525 + -26x + -1x2 = 26x + -26x + x2 + -1x2 Combine like terms: 26x + -26x = 0 525 + -26x + -1x2 = 0 + x2 + -1x2 525 + -26x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 525 + -26x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -525 + 26x + x2 = 0 Move the constant term to the right: Add '525' to each side of the equation. -525 + 26x + 525 + x2 = 0 + 525 Reorder the terms: -525 + 525 + 26x + x2 = 0 + 525 Combine like terms: -525 + 525 = 0 0 + 26x + x2 = 0 + 525 26x + x2 = 0 + 525 Combine like terms: 0 + 525 = 525 26x + x2 = 525 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 = 525 + 169 Reorder the terms: 169 + 26x + x2 = 525 + 169 Combine like terms: 525 + 169 = 694 169 + 26x + x2 = 694 Factor a perfect square on the left side: (x + 13)(x + 13) = 694 Calculate the square root of the right side: 26.343879745 Break this problem into two subproblems by setting (x + 13) equal to 26.343879745 and -26.343879745.Subproblem 1
x + 13 = 26.343879745 Simplifying x + 13 = 26.343879745 Reorder the terms: 13 + x = 26.343879745 Solving 13 + x = 26.343879745 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + x = 26.343879745 + -13 Combine like terms: 13 + -13 = 0 0 + x = 26.343879745 + -13 x = 26.343879745 + -13 Combine like terms: 26.343879745 + -13 = 13.343879745 x = 13.343879745 Simplifying x = 13.343879745Subproblem 2
x + 13 = -26.343879745 Simplifying x + 13 = -26.343879745 Reorder the terms: 13 + x = -26.343879745 Solving 13 + x = -26.343879745 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + x = -26.343879745 + -13 Combine like terms: 13 + -13 = 0 0 + x = -26.343879745 + -13 x = -26.343879745 + -13 Combine like terms: -26.343879745 + -13 = -39.343879745 x = -39.343879745 Simplifying x = -39.343879745Solution
The solution to the problem is based on the solutions from the subproblems. x = {13.343879745, -39.343879745}
