Q. Expand.Your answer should be a polynomial in standard form.
- Recognize the pattern: Recognize the pattern in the expression .This expression is a difference of squares, which follows the pattern .
- Apply the difference of squares formula: Apply the difference of squares formula.Here, is and is . So, we have:
- Calculate the squares: Calculate the squares of and .
- Subtract the squares: Subtract the square of from the square of .
- Write the final answer in standard form: Write the final answer in standard form.The standard form of a polynomial is written with the highest degree term first, followed by lower degree terms in descending order. Since we only have one term with and a constant term, the standard form is:
