Simplifying x2 + -11x + 240 = 0 Reorder the terms: 240 + -11x + x2 = 0 Solving 240 + -11x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-240' to each side of the equation. 240 + -11x + -240 + x2 = 0 + -240 Reorder the terms: 240 + -240 + -11x + x2 = 0 + -240 Combine like terms: 240 + -240 = 0 0 + -11x + x2 = 0 + -240 -11x + x2 = 0 + -240 Combine like terms: 0 + -240 = -240 -11x + x2 = -240 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 = -240 + 30.25 Reorder the terms: 30.25 + -11x + x2 = -240 + 30.25 Combine like terms: -240 + 30.25 = -209.75 30.25 + -11x + x2 = -209.75 Factor a perfect square on the left side: (x + -5.5)(x + -5.5) = -209.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
