Simplifying y2 + 14y + 98 = 0 Reorder the terms: 98 + 14y + y2 = 0 Solving 98 + 14y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-98' to each side of the equation. 98 + 14y + -98 + y2 = 0 + -98 Reorder the terms: 98 + -98 + 14y + y2 = 0 + -98 Combine like terms: 98 + -98 = 0 0 + 14y + y2 = 0 + -98 14y + y2 = 0 + -98 Combine like terms: 0 + -98 = -98 14y + y2 = -98 The y term is 14y. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14y + 49 + y2 = -98 + 49 Reorder the terms: 49 + 14y + y2 = -98 + 49 Combine like terms: -98 + 49 = -49 49 + 14y + y2 = -49 Factor a perfect square on the left side: (y + 7)(y + 7) = -49 Can't calculate square root of the right side. The solution to this equation could not be determined.
