To multiply $(4s + 4)$ by $(5s^3 - 4s^2 + 2s - 4)$, distribute each term in the first polynomial across the second polynomial:- $4s \times 5s^3 = 20s^4$- $4s \times (-4s^2) = -16s^3$- $4s \times 2s = 8s^2$- $4s \times (-4) = -16s$- $4 \times 5s^3 = 20s^3$- $4 \times (-4s^2) = -16s^2$- $4 \times 2s = 8s$- $4 \times (-4) = -16$Combine like terms:- $20s^4$- $(-16s^3 + 20s^3) = 4s^3$- $(8s^2 - 16s^2) = -8s^2$- $(-16s + 8s) = -8s$- $-16$So, the correct answer is $20s^4 + 4s^3 - 8s^2 - 8s - 16$.
