Did you know that polynomials like the one you’re working with can be simplified by combining like terms? In your expression \( (-2a + 10ab) \), you notice that you have terms involving the variables \( a \) and \( b \). Simplifying it helps in various mathematical applications, including solving algebraic equations or graphing functions. Finding common mistakes can significantly enhance your understanding! A common error when simplifying is to forget that \( a \) and \( ab \) are not like terms, so they cannot be combined. Always check to ensure you only add or subtract coefficients of the same variables to avoid such pitfalls. Keep practicing, and you'll get the hang of it!
