Simplifying y2 + 6y + 18 = 0 Reorder the terms: 18 + 6y + y2 = 0 Solving 18 + 6y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + 6y + -18 + y2 = 0 + -18 Reorder the terms: 18 + -18 + 6y + y2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + 6y + y2 = 0 + -18 6y + y2 = 0 + -18 Combine like terms: 0 + -18 = -18 6y + y2 = -18 The y term is 6y. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6y + 9 + y2 = -18 + 9 Reorder the terms: 9 + 6y + y2 = -18 + 9 Combine like terms: -18 + 9 = -9 9 + 6y + y2 = -9 Factor a perfect square on the left side: (y + 3)(y + 3) = -9 Can't calculate square root of the right side. The solution to this equation could not be determined.
