Simplifying 450 + -2X + X2 = 0 Solving 450 + -2X + X2 = 0 Solving for variable 'X'. Begin completing the square. Move the constant term to the right: Add '-450' to each side of the equation. 450 + -2X + -450 + X2 = 0 + -450 Reorder the terms: 450 + -450 + -2X + X2 = 0 + -450 Combine like terms: 450 + -450 = 0 0 + -2X + X2 = 0 + -450 -2X + X2 = 0 + -450 Combine like terms: 0 + -450 = -450 -2X + X2 = -450 The X term is -2X. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2X + 1 + X2 = -450 + 1 Reorder the terms: 1 + -2X + X2 = -450 + 1 Combine like terms: -450 + 1 = -449 1 + -2X + X2 = -449 Factor a perfect square on the left side: (X + -1)(X + -1) = -449 Can't calculate square root of the right side. The solution to this equation could not be determined.
