Simplifying X2 + -11X + 45 = 0 Reorder the terms: 45 + -11X + X2 = 0 Solving 45 + -11X + X2 = 0 Solving for variable 'X'. Begin completing the square. Move the constant term to the right: Add '-45' to each side of the equation. 45 + -11X + -45 + X2 = 0 + -45 Reorder the terms: 45 + -45 + -11X + X2 = 0 + -45 Combine like terms: 45 + -45 = 0 0 + -11X + X2 = 0 + -45 -11X + X2 = 0 + -45 Combine like terms: 0 + -45 = -45 -11X + X2 = -45 The X term is -11X. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11X + 30.25 + X2 = -45 + 30.25 Reorder the terms: 30.25 + -11X + X2 = -45 + 30.25 Combine like terms: -45 + 30.25 = -14.75 30.25 + -11X + X2 = -14.75 Factor a perfect square on the left side: (X + -5.5)(X + -5.5) = -14.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
