Simplifying x2 + -45x + 550 = 0 Reorder the terms: 550 + -45x + x2 = 0 Solving 550 + -45x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-550' to each side of the equation. 550 + -45x + -550 + x2 = 0 + -550 Reorder the terms: 550 + -550 + -45x + x2 = 0 + -550 Combine like terms: 550 + -550 = 0 0 + -45x + x2 = 0 + -550 -45x + x2 = 0 + -550 Combine like terms: 0 + -550 = -550 -45x + x2 = -550 The x term is -45x. Take half its coefficient (-22.5). Square it (506.25) and add it to both sides. Add '506.25' to each side of the equation. -45x + 506.25 + x2 = -550 + 506.25 Reorder the terms: 506.25 + -45x + x2 = -550 + 506.25 Combine like terms: -550 + 506.25 = -43.75 506.25 + -45x + x2 = -43.75 Factor a perfect square on the left side: (x + -22.5)(x + -22.5) = -43.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
