Answer:

the answer is #2x^2+7x+3#

Explanation:

just multiply them by each other. so #2x to x and 2x to 3# and make sure you get all the numbers. now do the same for the second number. you'll get #2x^2+6x+x+3# don't factor b/c it's already in factored form, you want the whole equation. so you add like terms and the only one you can add is #6x+x# so then you get #2x^2+7x+3#
