Simplifying x2 + 2.6x + 1.69 = 0 Reorder the terms: 1.69 + 2.6x + x2 = 0 Solving 1.69 + 2.6x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-1.69' to each side of the equation. 1.69 + 2.6x + -1.69 + x2 = 0 + -1.69 Reorder the terms: 1.69 + -1.69 + 2.6x + x2 = 0 + -1.69 Combine like terms: 1.69 + -1.69 = 0.00 0.00 + 2.6x + x2 = 0 + -1.69 2.6x + x2 = 0 + -1.69 Combine like terms: 0 + -1.69 = -1.69 2.6x + x2 = -1.69 The x term is 2.6x. Take half its coefficient (1.3). Square it (1.69) and add it to both sides. Add '1.69' to each side of the equation. 2.6x + 1.69 + x2 = -1.69 + 1.69 Reorder the terms: 1.69 + 2.6x + x2 = -1.69 + 1.69 Combine like terms: -1.69 + 1.69 = 0.00 1.69 + 2.6x + x2 = 0.00 Factor a perfect square on the left side: (x + 1.3)(x + 1.3) = 0.00 Calculate the square root of the right side: 0.00 Break this problem into two subproblems by setting (x + 1.3) equal to 0.00 and 0.00.Subproblem 1
x + 1.3 = 0.00 Simplifying x + 1.3 = 0.00 Reorder the terms: 1.3 + x = 0.00 Solving 1.3 + x = 0.00 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.3' to each side of the equation. 1.3 + -1.3 + x = 0.00 + -1.3 Combine like terms: 1.3 + -1.3 = 0.0 0.0 + x = 0.00 + -1.3 x = 0.00 + -1.3 Combine like terms: 0.00 + -1.3 = -1.3 x = -1.3 Simplifying x = -1.3Subproblem 2
x + 1.3 = 0.00 Simplifying x + 1.3 = 0.00 Reorder the terms: 1.3 + x = 0.00 Solving 1.3 + x = 0.00 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.3' to each side of the equation. 1.3 + -1.3 + x = 0.00 + -1.3 Combine like terms: 1.3 + -1.3 = 0.0 0.0 + x = 0.00 + -1.3 x = 0.00 + -1.3 Combine like terms: 0.00 + -1.3 = -1.3 x = -1.3 Simplifying x = -1.3Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.3, -1.3}
