Simplifying 40 + x = 2x(9 + x) 40 + x = (9 * 2x + x * 2x) 40 + x = (18x + 2x2) Solving 40 + x = 18x + 2x2 Solving for variable 'x'. Combine like terms: x + -18x = -17x 40 + -17x + -2x2 = 18x + 2x2 + -18x + -2x2 Reorder the terms: 40 + -17x + -2x2 = 18x + -18x + 2x2 + -2x2 Combine like terms: 18x + -18x = 0 40 + -17x + -2x2 = 0 + 2x2 + -2x2 40 + -17x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 40 + -17x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -20 + 8.5x + x2 = 0 Move the constant term to the right: Add '20' to each side of the equation. -20 + 8.5x + 20 + x2 = 0 + 20 Reorder the terms: -20 + 20 + 8.5x + x2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + 8.5x + x2 = 0 + 20 8.5x + x2 = 0 + 20 Combine like terms: 0 + 20 = 20 8.5x + x2 = 20 The x term is 8.5x. Take half its coefficient (4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. 8.5x + 18.0625 + x2 = 20 + 18.0625 Reorder the terms: 18.0625 + 8.5x + x2 = 20 + 18.0625 Combine like terms: 20 + 18.0625 = 38.0625 18.0625 + 8.5x + x2 = 38.0625 Factor a perfect square on the left side: (x + 4.25)(x + 4.25) = 38.0625 Calculate the square root of the right side: 6.16948134 Break this problem into two subproblems by setting (x + 4.25) equal to 6.16948134 and -6.16948134.Subproblem 1
x + 4.25 = 6.16948134 Simplifying x + 4.25 = 6.16948134 Reorder the terms: 4.25 + x = 6.16948134 Solving 4.25 + x = 6.16948134 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + x = 6.16948134 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = 6.16948134 + -4.25 x = 6.16948134 + -4.25 Combine like terms: 6.16948134 + -4.25 = 1.91948134 x = 1.91948134 Simplifying x = 1.91948134Subproblem 2
x + 4.25 = -6.16948134 Simplifying x + 4.25 = -6.16948134 Reorder the terms: 4.25 + x = -6.16948134 Solving 4.25 + x = -6.16948134 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + x = -6.16948134 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = -6.16948134 + -4.25 x = -6.16948134 + -4.25 Combine like terms: -6.16948134 + -4.25 = -10.41948134 x = -10.41948134 Simplifying x = -10.41948134Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.91948134, -10.41948134}
