Asked by dude

this is the question:
what's the product of (2q^9+3q^7)(-6q^2+9)

list the polynomial (product) in descending order


what do I write for the answer
(2q^9+3q^7)(-6q^2+9) = -12q^11 + 27q^7
do I include everything including the parenthesis or just the last polynomial?

Your multiplication is correct:

(2q^9 + 3q^7)(-6q^2 + 9) = -12q^11 + 27q^7.

Write the final answer as the polynomial in descending powers (largest exponent first): -12q^11 + 27q^7. You do not need to keep the parentheses unless you are asked to show the product in factored form. (If you wanted a factored form, you could write 3q^7(9 − 4q^4).)
