Simplifying y2 + -1y + 18 = 0 Reorder the terms: 18 + -1y + y2 = 0 Solving 18 + -1y + 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 + -1y + -18 + y2 = 0 + -18 Reorder the terms: 18 + -18 + -1y + y2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + -1y + y2 = 0 + -18 -1y + y2 = 0 + -18 Combine like terms: 0 + -18 = -18 -1y + y2 = -18 The y term is -1y. 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. -1y + 0.25 + y2 = -18 + 0.25 Reorder the terms: 0.25 + -1y + y2 = -18 + 0.25 Combine like terms: -18 + 0.25 = -17.75 0.25 + -1y + y2 = -17.75 Factor a perfect square on the left side: (y + -0.5)(y + -0.5) = -17.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
