use the remainder theorem to find the remainder when f(x) is divided by x2. then use the factor theorem to divide x2 is a factor of f(x).
f(x)=4x^47x^35x+2
the remainder is ?
is x2 a remainder of f(x)=4x^47x^35x+2
please show work

college algebra, Please help!! 
Reiny,
check your typing.
Were you asking ...
is x2 a factor of f(x) .... ?
f(2) = 4(2^4)  7(2^3)  5(2) + 2
= 64  56  10 + 2 = 0
yes, x2 is a factor.
