Full solution
Q. Expand.Your answer should be a polynomial in standard form.
- Apply distributive property: Apply the distributive property (also known as the FOIL method) to expand the expression .First, multiply the first terms in each binomial: .Next, multiply the outer terms: .Then, multiply the inner terms: .Finally, multiply the last terms: .
- Combine like terms: Combine the like terms from the expansion.We have from the first terms, and from the outer and inner terms, and from the last terms.Combine and to get .So, the expression becomes .
- Write final answer in standard form: Write the final answer in standard form, which is a polynomial arranged in descending order of degree.The standard form of the expanded polynomial is .
