Simplifying 6x2 + 18x + -11 = 0 Reorder the terms: -11 + 18x + 6x2 = 0 Solving -11 + 18x + 6x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. -1.833333333 + 3x + x2 = 0 Move the constant term to the right: Add '1.833333333' to each side of the equation. -1.833333333 + 3x + 1.833333333 + x2 = 0 + 1.833333333 Reorder the terms: -1.833333333 + 1.833333333 + 3x + x2 = 0 + 1.833333333 Combine like terms: -1.833333333 + 1.833333333 = 0.000000000 0.000000000 + 3x + x2 = 0 + 1.833333333 3x + x2 = 0 + 1.833333333 Combine like terms: 0 + 1.833333333 = 1.833333333 3x + x2 = 1.833333333 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 1.833333333 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 1.833333333 + 2.25 Combine like terms: 1.833333333 + 2.25 = 4.083333333 2.25 + 3x + x2 = 4.083333333 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 4.083333333 Calculate the square root of the right side: 2.020725942 Break this problem into two subproblems by setting (x + 1.5) equal to 2.020725942 and -2.020725942.Subproblem 1
x + 1.5 = 2.020725942 Simplifying x + 1.5 = 2.020725942 Reorder the terms: 1.5 + x = 2.020725942 Solving 1.5 + x = 2.020725942 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 2.020725942 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 2.020725942 + -1.5 x = 2.020725942 + -1.5 Combine like terms: 2.020725942 + -1.5 = 0.520725942 x = 0.520725942 Simplifying x = 0.520725942Subproblem 2
x + 1.5 = -2.020725942 Simplifying x + 1.5 = -2.020725942 Reorder the terms: 1.5 + x = -2.020725942 Solving 1.5 + x = -2.020725942 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -2.020725942 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -2.020725942 + -1.5 x = -2.020725942 + -1.5 Combine like terms: -2.020725942 + -1.5 = -3.520725942 x = -3.520725942 Simplifying x = -3.520725942Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.520725942, -3.520725942}
