Simplifying x2 + -13x + 45 = 0 Reorder the terms: 45 + -13x + x2 = 0 Solving 45 + -13x + 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 + -13x + -45 + x2 = 0 + -45 Reorder the terms: 45 + -45 + -13x + x2 = 0 + -45 Combine like terms: 45 + -45 = 0 0 + -13x + x2 = 0 + -45 -13x + x2 = 0 + -45 Combine like terms: 0 + -45 = -45 -13x + x2 = -45 The x term is -13x. Take half its coefficient (-6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. -13x + 42.25 + x2 = -45 + 42.25 Reorder the terms: 42.25 + -13x + x2 = -45 + 42.25 Combine like terms: -45 + 42.25 = -2.75 42.25 + -13x + x2 = -2.75 Factor a perfect square on the left side: (x + -6.5)(x + -6.5) = -2.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
