Need ! the product of the polynomials (2ab + b) and (a2 – b2) is 2a3b-2ab3+a2b-b3 . if this product is multiplied by (2a + b), the result is a polynomial with terms.

Can someone answer it, and plot it, for 20 points and brainliest answer? p.s. they're the same ! : )

3-12. write each answer with a reasonable number of figures. find the absolute uncertainty and percent relative uncertainty for each answer. (a) [12.41 (±0.09) + 4.16 (±0.01)] x 7.068 2 (±0.000 4) =? (b) [3.26 (±0.10) x 8.47 (±0.05)] - 0.18 (±0.06) =? (c) 6.843 (±0.008) x 104 + [2.09 (±0.04)- 1.63 (±0.01)] =?
