Simplifying x2 + 0.1x + -0.3 = 0 Reorder the terms: -0.3 + 0.1x + x2 = 0 Solving -0.3 + 0.1x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.3' to each side of the equation. -0.3 + 0.1x + 0.3 + x2 = 0 + 0.3 Reorder the terms: -0.3 + 0.3 + 0.1x + x2 = 0 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + 0.1x + x2 = 0 + 0.3 0.1x + x2 = 0 + 0.3 Combine like terms: 0 + 0.3 = 0.3 0.1x + x2 = 0.3 The x term is 0.1x. Take half its coefficient (0.05). Square it (0.0025) and add it to both sides. Add '0.0025' to each side of the equation. 0.1x + 0.0025 + x2 = 0.3 + 0.0025 Reorder the terms: 0.0025 + 0.1x + x2 = 0.3 + 0.0025 Combine like terms: 0.3 + 0.0025 = 0.3025 0.0025 + 0.1x + x2 = 0.3025 Factor a perfect square on the left side: (x + 0.05)(x + 0.05) = 0.3025 Calculate the square root of the right side: 0.55 Break this problem into two subproblems by setting (x + 0.05) equal to 0.55 and -0.55.Subproblem 1
x + 0.05 = 0.55 Simplifying x + 0.05 = 0.55 Reorder the terms: 0.05 + x = 0.55 Solving 0.05 + x = 0.55 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.05' to each side of the equation. 0.05 + -0.05 + x = 0.55 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + x = 0.55 + -0.05 x = 0.55 + -0.05 Combine like terms: 0.55 + -0.05 = 0.5 x = 0.5 Simplifying x = 0.5Subproblem 2
x + 0.05 = -0.55 Simplifying x + 0.05 = -0.55 Reorder the terms: 0.05 + x = -0.55 Solving 0.05 + x = -0.55 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.05' to each side of the equation. 0.05 + -0.05 + x = -0.55 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + x = -0.55 + -0.05 x = -0.55 + -0.05 Combine like terms: -0.55 + -0.05 = -0.6 x = -0.6 Simplifying x = -0.6Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.5, -0.6}
