(a0+a1*x+a2*x^2)(b0+b1*x+b2*x^2)
Now, rearrange them in descending powers of x
(a2x^2+a1x+ao)(b2x^2+b1x+bo) Now follow this example

Next, multiply the second term of the first trinomial with each term of the second trinomial. Finally, multiply the third term of the first trinomial with each term of the second trinomial. Hence, the product of (2x2 + 2x + 1) and (3x2 + 5x + 2) is 6x4 + 16 x3 + 17x2 + 9x + 2.
NOTE: before you answer this question, please be aware that there aren't meant to be any full stops after the '2' or the 'i=0'. Also the underscores '-' represent how the following number is meant to be a lower case number. The ^ represents root numbers. PLEASE HELP ME
Expand the following polynomial and write it in standard form:
2. 2
(∑ a_i x^i )(∑ b_j x^j )
i=0. j=0
