Simplifying y2 + 20y + 352 = 0 Reorder the terms: 352 + 20y + y2 = 0 Solving 352 + 20y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-352' to each side of the equation. 352 + 20y + -352 + y2 = 0 + -352 Reorder the terms: 352 + -352 + 20y + y2 = 0 + -352 Combine like terms: 352 + -352 = 0 0 + 20y + y2 = 0 + -352 20y + y2 = 0 + -352 Combine like terms: 0 + -352 = -352 20y + y2 = -352 The y term is 20y. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20y + 100 + y2 = -352 + 100 Reorder the terms: 100 + 20y + y2 = -352 + 100 Combine like terms: -352 + 100 = -252 100 + 20y + y2 = -252 Factor a perfect square on the left side: (y + 10)(y + 10) = -252 Can't calculate square root of the right side. The solution to this equation could not be determined.
