Quizplus · Accepted Answer

To multiply the given polynomials, each term in the first polynomial is multiplied by each term in the second polynomial and then the results are added together. The multiplication is as follows: $(-5m^2)(-5m) = 25m^3$, $(-5m^2)(2) = -10m^2$, $(m)(-5m) = -5m^2$, $(m)(2) = 2m$, $(7)(-5m) = -35m$, and $(7)(2) = 14$. Adding these results together gives $25m^3 + (-10m^2 - 5m^2) + (-35m + 2m) + 14 = 25m^3 - 15m^2 - 33m + 14$.
