Simplifying (9x2) + -18x + 9 = 47 Reorder the terms: 9 + -18x + (9x2) = 47 Solving 9 + -18x + (9x2) = 47 Solving for variable 'x'. Reorder the terms: 9 + -47 + -18x + (9x2) = 47 + -47 Combine like terms: 9 + -47 = -38 -38 + -18x + (9x2) = 47 + -47 Combine like terms: 47 + -47 = 0 -38 + -18x + (9x2) = 0 Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. -4.222222222 + -2x + x2 = 0 Move the constant term to the right: Add '4.222222222' to each side of the equation. -4.222222222 + -2x + 4.222222222 + x2 = 0 + 4.222222222 Reorder the terms: -4.222222222 + 4.222222222 + -2x + x2 = 0 + 4.222222222 Combine like terms: -4.222222222 + 4.222222222 = 0.000000000 0.000000000 + -2x + x2 = 0 + 4.222222222 -2x + x2 = 0 + 4.222222222 Combine like terms: 0 + 4.222222222 = 4.222222222 -2x + x2 = 4.222222222 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 4.222222222 + 1 Reorder the terms: 1 + -2x + x2 = 4.222222222 + 1 Combine like terms: 4.222222222 + 1 = 5.222222222 1 + -2x + x2 = 5.222222222 Factor a perfect square on the left side: ((x) + -1)((x) + -1) = 5.222222222 Calculate the square root of the right side: 2.2852182 Break this problem into two subproblems by setting ((x) + -1) equal to 2.2852182 and -2.2852182.Subproblem 1
(x) + -1 = 2.2852182 Simplifying (x) + -1 = 2.2852182 x + -1 = 2.2852182 Reorder the terms: -1 + x = 2.2852182 Solving -1 + x = 2.2852182 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 2.2852182 + 1 Combine like terms: -1 + 1 = 0 0 + x = 2.2852182 + 1 x = 2.2852182 + 1 Combine like terms: 2.2852182 + 1 = 3.2852182 x = 3.2852182 Simplifying x = 3.2852182Subproblem 2
(x) + -1 = -2.2852182 Simplifying (x) + -1 = -2.2852182 x + -1 = -2.2852182 Reorder the terms: -1 + x = -2.2852182 Solving -1 + x = -2.2852182 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -2.2852182 + 1 Combine like terms: -1 + 1 = 0 0 + x = -2.2852182 + 1 x = -2.2852182 + 1 Combine like terms: -2.2852182 + 1 = -1.2852182 x = -1.2852182 Simplifying x = -1.2852182Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.2852182, -1.2852182}
