Simplifying X2 + -9X + 2510 = 0 Reorder the terms: 2510 + -9X + X2 = 0 Solving 2510 + -9X + X2 = 0 Solving for variable 'X'. Begin completing the square. Move the constant term to the right: Add '-2510' to each side of the equation. 2510 + -9X + -2510 + X2 = 0 + -2510 Reorder the terms: 2510 + -2510 + -9X + X2 = 0 + -2510 Combine like terms: 2510 + -2510 = 0 0 + -9X + X2 = 0 + -2510 -9X + X2 = 0 + -2510 Combine like terms: 0 + -2510 = -2510 -9X + X2 = -2510 The X term is -9X. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9X + 20.25 + X2 = -2510 + 20.25 Reorder the terms: 20.25 + -9X + X2 = -2510 + 20.25 Combine like terms: -2510 + 20.25 = -2489.75 20.25 + -9X + X2 = -2489.75 Factor a perfect square on the left side: (X + -4.5)(X + -4.5) = -2489.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
