VERY IMPORTSNT PLEASE Find the roots of the polynomial function: f(x)= (x+5)(x-3)(x-1)

A.
x=5, x=-3, x=-1
B.
x= -5, x=3, x=1
C.
x=5, x=3, x=1
D.
x=-5, x=-3, x=-1

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.
