Simplifying x2 + -0.38x + 0.046 = 0 Reorder the terms: 0.046 + -0.38x + x2 = 0 Solving 0.046 + -0.38x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-0.046' to each side of the equation. 0.046 + -0.38x + -0.046 + x2 = 0 + -0.046 Reorder the terms: 0.046 + -0.046 + -0.38x + x2 = 0 + -0.046 Combine like terms: 0.046 + -0.046 = 0.000 0.000 + -0.38x + x2 = 0 + -0.046 -0.38x + x2 = 0 + -0.046 Combine like terms: 0 + -0.046 = -0.046 -0.38x + x2 = -0.046 The x term is -0.38x. Take half its coefficient (-0.19). Square it (0.0361) and add it to both sides. Add '0.0361' to each side of the equation. -0.38x + 0.0361 + x2 = -0.046 + 0.0361 Reorder the terms: 0.0361 + -0.38x + x2 = -0.046 + 0.0361 Combine like terms: -0.046 + 0.0361 = -0.0099 0.0361 + -0.38x + x2 = -0.0099 Factor a perfect square on the left side: (x + -0.19)(x + -0.19) = -0.0099 Can't calculate square root of the right side. The solution to this equation could not be determined.
