Simplifying (x * x) + -2x = 23 Multiply x * x (x2) + -2x = 23 x2 + -2x = 23 Reorder the terms: -2x + x2 = 23 Solving -2x + x2 = 23 Solving for variable 'x'. Reorder the terms: -23 + -2x + x2 = 23 + -23 Combine like terms: 23 + -23 = 0 -23 + -2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '23' to each side of the equation. -23 + -2x + 23 + x2 = 0 + 23 Reorder the terms: -23 + 23 + -2x + x2 = 0 + 23 Combine like terms: -23 + 23 = 0 0 + -2x + x2 = 0 + 23 -2x + x2 = 0 + 23 Combine like terms: 0 + 23 = 23 -2x + x2 = 23 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 = 23 + 1 Reorder the terms: 1 + -2x + x2 = 23 + 1 Combine like terms: 23 + 1 = 24 1 + -2x + x2 = 24 Factor a perfect square on the left side: (x + -1)(x + -1) = 24 Calculate the square root of the right side: 4.898979486 Break this problem into two subproblems by setting (x + -1) equal to 4.898979486 and -4.898979486.Subproblem 1
x + -1 = 4.898979486 Simplifying x + -1 = 4.898979486 Reorder the terms: -1 + x = 4.898979486 Solving -1 + x = 4.898979486 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 = 4.898979486 + 1 Combine like terms: -1 + 1 = 0 0 + x = 4.898979486 + 1 x = 4.898979486 + 1 Combine like terms: 4.898979486 + 1 = 5.898979486 x = 5.898979486 Simplifying x = 5.898979486Subproblem 2
x + -1 = -4.898979486 Simplifying x + -1 = -4.898979486 Reorder the terms: -1 + x = -4.898979486 Solving -1 + x = -4.898979486 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 = -4.898979486 + 1 Combine like terms: -1 + 1 = 0 0 + x = -4.898979486 + 1 x = -4.898979486 + 1 Combine like terms: -4.898979486 + 1 = -3.898979486 x = -3.898979486 Simplifying x = -3.898979486Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.898979486, -3.898979486}
