Simplifying x2 + 22x + -3 = 0 Reorder the terms: -3 + 22x + x2 = 0 Solving -3 + 22x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + 22x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + 22x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 22x + x2 = 0 + 3 22x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 22x + x2 = 3 The x term is 22x. Take half its coefficient (11). Square it (121) and add it to both sides. Add '121' to each side of the equation. 22x + 121 + x2 = 3 + 121 Reorder the terms: 121 + 22x + x2 = 3 + 121 Combine like terms: 3 + 121 = 124 121 + 22x + x2 = 124 Factor a perfect square on the left side: (x + 11)(x + 11) = 124 Calculate the square root of the right side: 11.135528726 Break this problem into two subproblems by setting (x + 11) equal to 11.135528726 and -11.135528726.Subproblem 1
x + 11 = 11.135528726 Simplifying x + 11 = 11.135528726 Reorder the terms: 11 + x = 11.135528726 Solving 11 + x = 11.135528726 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + x = 11.135528726 + -11 Combine like terms: 11 + -11 = 0 0 + x = 11.135528726 + -11 x = 11.135528726 + -11 Combine like terms: 11.135528726 + -11 = 0.135528726 x = 0.135528726 Simplifying x = 0.135528726Subproblem 2
x + 11 = -11.135528726 Simplifying x + 11 = -11.135528726 Reorder the terms: 11 + x = -11.135528726 Solving 11 + x = -11.135528726 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + x = -11.135528726 + -11 Combine like terms: 11 + -11 = 0 0 + x = -11.135528726 + -11 x = -11.135528726 + -11 Combine like terms: -11.135528726 + -11 = -22.135528726 x = -22.135528726 Simplifying x = -22.135528726Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.135528726, -22.135528726}
