RATIONALE
To multiply these two polynomials, you can

distribute into each of the terms inside the

parentheses. First, distribute into .

, When multiplying these two terms, you will multiply the
coefficients together and evaluate the multiplication of the
x-terms.
The coefficients 7 and 2 multiply to 14. Recall that if two
terms with the same base are multiplied, simply add the

exponents, so times equals . Don't forget to

include the . Next, distribute into .
Similar to above, when multiplying these two terms, you
will multiply the coefficients together and evaluate the
multiplication of the x-terms.


The coefficients of 7 and 3 multiply to 21. The

times equals . Don't forget to include the one factor of
y. Finally, add both parts together.
The final product is the sum of the two distributions.
