Question

check whether the polynomials f(x) is a factor of f(x) or not in each of the following:

Answer 1

Take g(x) =0,
U will find a value a value of x..(it will be 2/5)
After that, put the value of x in f(x)..
After putting the value of x in f(x), if f(x) becomes 0 then f(x) is divisible by g(x), and if it is other than 0, f(x) is not divisible by g(x)

Told u the process, do it urself, u could understand better and hope it helps..
