Simplifying y2 + 22y + 217 = 0 Reorder the terms: 217 + 22y + y2 = 0 Solving 217 + 22y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-217' to each side of the equation. 217 + 22y + -217 + y2 = 0 + -217 Reorder the terms: 217 + -217 + 22y + y2 = 0 + -217 Combine like terms: 217 + -217 = 0 0 + 22y + y2 = 0 + -217 22y + y2 = 0 + -217 Combine like terms: 0 + -217 = -217 22y + y2 = -217 The y term is 22y. Take half its coefficient (11). Square it (121) and add it to both sides. Add '121' to each side of the equation. 22y + 121 + y2 = -217 + 121 Reorder the terms: 121 + 22y + y2 = -217 + 121 Combine like terms: -217 + 121 = -96 121 + 22y + y2 = -96 Factor a perfect square on the left side: (y + 11)(y + 11) = -96 Can't calculate square root of the right side. The solution to this equation could not be determined.
