Simplifying X2 + -2.6X + 2.01 = 0 Reorder the terms: 2.01 + -2.6X + X2 = 0 Solving 2.01 + -2.6X + X2 = 0 Solving for variable 'X'. Begin completing the square. Move the constant term to the right: Add '-2.01' to each side of the equation. 2.01 + -2.6X + -2.01 + X2 = 0 + -2.01 Reorder the terms: 2.01 + -2.01 + -2.6X + X2 = 0 + -2.01 Combine like terms: 2.01 + -2.01 = 0.00 0.00 + -2.6X + X2 = 0 + -2.01 -2.6X + X2 = 0 + -2.01 Combine like terms: 0 + -2.01 = -2.01 -2.6X + X2 = -2.01 The X term is -2.6X. Take half its coefficient (-1.3). Square it (1.69) and add it to both sides. Add '1.69' to each side of the equation. -2.6X + 1.69 + X2 = -2.01 + 1.69 Reorder the terms: 1.69 + -2.6X + X2 = -2.01 + 1.69 Combine like terms: -2.01 + 1.69 = -0.32 1.69 + -2.6X + X2 = -0.32 Factor a perfect square on the left side: (X + -1.3)(X + -1.3) = -0.32 Can't calculate square root of the right side. The solution to this equation could not be determined.
