Simplifying x2 + -1x + 98 = 0 Reorder the terms: 98 + -1x + x2 = 0 Solving 98 + -1x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-98' to each side of the equation. 98 + -1x + -98 + x2 = 0 + -98 Reorder the terms: 98 + -98 + -1x + x2 = 0 + -98 Combine like terms: 98 + -98 = 0 0 + -1x + x2 = 0 + -98 -1x + x2 = 0 + -98 Combine like terms: 0 + -98 = -98 -1x + x2 = -98 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -98 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -98 + 0.25 Combine like terms: -98 + 0.25 = -97.75 0.25 + -1x + x2 = -97.75 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -97.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
