Simplifying x2 + 0.6x + -0.4 = 0 Reorder the terms: -0.4 + 0.6x + x2 = 0 Solving -0.4 + 0.6x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.4' to each side of the equation. -0.4 + 0.6x + 0.4 + x2 = 0 + 0.4 Reorder the terms: -0.4 + 0.4 + 0.6x + x2 = 0 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + 0.6x + x2 = 0 + 0.4 0.6x + x2 = 0 + 0.4 Combine like terms: 0 + 0.4 = 0.4 0.6x + x2 = 0.4 The x term is 0.6x. Take half its coefficient (0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. 0.6x + 0.09 + x2 = 0.4 + 0.09 Reorder the terms: 0.09 + 0.6x + x2 = 0.4 + 0.09 Combine like terms: 0.4 + 0.09 = 0.49 0.09 + 0.6x + x2 = 0.49 Factor a perfect square on the left side: (x + 0.3)(x + 0.3) = 0.49 Calculate the square root of the right side: 0.7 Break this problem into two subproblems by setting (x + 0.3) equal to 0.7 and -0.7.Subproblem 1
x + 0.3 = 0.7 Simplifying x + 0.3 = 0.7 Reorder the terms: 0.3 + x = 0.7 Solving 0.3 + x = 0.7 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = 0.7 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = 0.7 + -0.3 x = 0.7 + -0.3 Combine like terms: 0.7 + -0.3 = 0.4 x = 0.4 Simplifying x = 0.4Subproblem 2
x + 0.3 = -0.7 Simplifying x + 0.3 = -0.7 Reorder the terms: 0.3 + x = -0.7 Solving 0.3 + x = -0.7 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = -0.7 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = -0.7 + -0.3 x = -0.7 + -0.3 Combine like terms: -0.7 + -0.3 = -1 x = -1 Simplifying x = -1Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.4, -1}
