Simplifying x2 + -0.36x + 0.16 = 0 Reorder the terms: 0.16 + -0.36x + x2 = 0 Solving 0.16 + -0.36x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-0.16' to each side of the equation. 0.16 + -0.36x + -0.16 + x2 = 0 + -0.16 Reorder the terms: 0.16 + -0.16 + -0.36x + x2 = 0 + -0.16 Combine like terms: 0.16 + -0.16 = 0.00 0.00 + -0.36x + x2 = 0 + -0.16 -0.36x + x2 = 0 + -0.16 Combine like terms: 0 + -0.16 = -0.16 -0.36x + x2 = -0.16 The x term is -0.36x. Take half its coefficient (-0.18). Square it (0.0324) and add it to both sides. Add '0.0324' to each side of the equation. -0.36x + 0.0324 + x2 = -0.16 + 0.0324 Reorder the terms: 0.0324 + -0.36x + x2 = -0.16 + 0.0324 Combine like terms: -0.16 + 0.0324 = -0.1276 0.0324 + -0.36x + x2 = -0.1276 Factor a perfect square on the left side: (x + -0.18)(x + -0.18) = -0.1276 Can't calculate square root of the right side. The solution to this equation could not be determined.
