Question

The value of polynomial p(x)=4x^2-5x-x^3 at p(0),p(-1)and p2/3) ​

Answer 1

hey mate............

here is ur answer.....

p[x]=-x3+4x2-5x

p[0]=[-0]3+4[0]2-5[0]

     =0+0-0

      =0

p[-1]=[-1]3+4[-1]2-5[-1]

     =-1+4+5

     =-1+9

     =8

p[2/3]=[-2/3]3+4[2/3]2-5[2/3]

         = -8/27+16/9-10/3

lcm of 27,9 and 3 is 27

   =[-8+48-90]/27

    =-50/27
