Question 755626
(a+3)(a+3)

For this problem, it is easier to use the FOIL method. FOIL stands for [F]irst [O]uter [I]nner [L]ast


So, multiply the first terms of each pair together: A*a=a^2


Then multiply the outer terms: a*3=3a


Next multiply the inner terms: 3*a=3a


Lastly multiply the last terms: 3*3=9


Now add them all together:


a^2+3a+3a+9

a^2+6a+9


Hope this helps!
