What must be subtracted from the polynomial f(x) = x4 + 2x3 - 13x2 - 12x + 21 so that the resulting polynomial is exactly divisible by x2 - 4x + 3 ?

pls do it urgently

the given polynomial is  is divided by



remainder is 2x-3

so if we will subtract 2x-3 from f(x), it will be exactly divisible by

hope this helps you.
