It seems like you're trying to write a mathematical expression or equation that includes the terms \( x^2 y \) and \( -y \). Can you please clarify what you'd like to do with these terms? Are you looking to simplify the expression, solve an equation, or something else? Here's a breakdown of the expression as it stands:
If you have the expression: \[ x^2 y - y \] You can factor out \( y \) from both terms: \[ y(x^2 - 1) \] If this is not what you were looking for, please provide more details!
