Simplifying x2 + 0.1x + -0.000893 = 0 Reorder the terms: -0.000893 + 0.1x + x2 = 0 Solving -0.000893 + 0.1x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.000893' to each side of the equation. -0.000893 + 0.1x + 0.000893 + x2 = 0 + 0.000893 Reorder the terms: -0.000893 + 0.000893 + 0.1x + x2 = 0 + 0.000893 Combine like terms: -0.000893 + 0.000893 = 0.000000 0.000000 + 0.1x + x2 = 0 + 0.000893 0.1x + x2 = 0 + 0.000893 Combine like terms: 0 + 0.000893 = 0.000893 0.1x + x2 = 0.000893 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 = 0.000893 + 0.0025 Reorder the terms: 0.0025 + 0.1x + x2 = 0.000893 + 0.0025 Combine like terms: 0.000893 + 0.0025 = 0.003393 0.0025 + 0.1x + x2 = 0.003393 Factor a perfect square on the left side: (x + 0.05)(x + 0.05) = 0.003393 Calculate the square root of the right side: 0.058249464 Break this problem into two subproblems by setting (x + 0.05) equal to 0.058249464 and -0.058249464.Subproblem 1
x + 0.05 = 0.058249464 Simplifying x + 0.05 = 0.058249464 Reorder the terms: 0.05 + x = 0.058249464 Solving 0.05 + x = 0.058249464 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 = 0.058249464 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + x = 0.058249464 + -0.05 x = 0.058249464 + -0.05 Combine like terms: 0.058249464 + -0.05 = 0.008249464 x = 0.008249464 Simplifying x = 0.008249464Subproblem 2
x + 0.05 = -0.058249464 Simplifying x + 0.05 = -0.058249464 Reorder the terms: 0.05 + x = -0.058249464 Solving 0.05 + x = -0.058249464 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 = -0.058249464 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + x = -0.058249464 + -0.05 x = -0.058249464 + -0.05 Combine like terms: -0.058249464 + -0.05 = -0.108249464 x = -0.108249464 Simplifying x = -0.108249464Solution
