The product of (x + 3)(-x2 + 4x − 2) is:

The product is -x^3+x^2+10x-6

Basically you multiply the second equation (-x^2+4x-2) by 3

Secondly you multiply that equation by the variable x

You then get -x^3+4x^2-2x-3x^2+12x-6

You collect your like terms and end up with the answer -x^3+x^2+10x-6

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
