The video tutorial explains how to simplify a polynomial expression by distributing a negative sign and combining like terms. It begins with rewriting the expression without unnecessary parentheses, then distributes the negative sign across the terms inside the parentheses. Finally, it combines terms with the same degree of x to achieve a simplified polynomial.

What is the first step in simplifying the given polynomial?

• Identify the highest degree term

• Distribute the negative sign

• Combine like terms

• Add the constants
