Question

determine what must be added to x^3-3x^2+4x-13 to obtain a polynomial which is exactly divisible by x-3

Answer 1

-1 should be the correct answer as by remainder theorem

Answer 2

x-3/x³-3x²+4x-13   [i think ur question is wrong because there must b 12 instead of 13]
then the polynomial will b x²+4  
                                         this will b ur answer hope uh admit ur mistake or recheck it
