first of all u have to write the value of f(x) and write its co-officeient .
then u write the given of zeroes . next u write the given relation . then u put the value of the co;officent and the value of k will come out 2.
then u write the given of zeroes . next u write the given relation . then u put the value of the co;officent and the value of k will come out 2.
