11x21

Explanation:

(8x2+1)+(3x22)

To simplify it we need to first get rid of the brackets.

8x2+1+3x22

Because the sign between two brackets is + therefore the sign in the second bracket (minus-) stays the same.

Then we add 8x2 and 3x2 together because they both have x2 in common and 1 and 2 because they are ordinary numbers.

8x2+3x2+12=
=11x21
