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

pls do it urgently

the given polynomial is is divided by

thus

remainder is 2x-3

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

hope this helps you.

cheers!!
