Simplifying x2 + -0.06x + 0.09 = 0 Reorder the terms: 0.09 + -0.06x + x2 = 0 Solving 0.09 + -0.06x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-0.09' to each side of the equation. 0.09 + -0.06x + -0.09 + x2 = 0 + -0.09 Reorder the terms: 0.09 + -0.09 + -0.06x + x2 = 0 + -0.09 Combine like terms: 0.09 + -0.09 = 0.00 0.00 + -0.06x + x2 = 0 + -0.09 -0.06x + x2 = 0 + -0.09 Combine like terms: 0 + -0.09 = -0.09 -0.06x + x2 = -0.09 The x term is -0.06x. Take half its coefficient (-0.03). Square it (0.0009) and add it to both sides. Add '0.0009' to each side of the equation. -0.06x + 0.0009 + x2 = -0.09 + 0.0009 Reorder the terms: 0.0009 + -0.06x + x2 = -0.09 + 0.0009 Combine like terms: -0.09 + 0.0009 = -0.0891 0.0009 + -0.06x + x2 = -0.0891 Factor a perfect square on the left side: (x + -0.03)(x + -0.03) = -0.0891 Can't calculate square root of the right side. The solution to this equation could not be determined.
