If the Degree of the Polynomial is N then CRC Generator will be of Degree N+1 bits And CRC Will be N bits.

The message is Given as M(x) = x7 + x4 + x3 + x Then Message bits  = 10011010

CRC Generator G(x) = x3 + x2 +1    =  1101

Then CRC(After performing XOR operation or Modulo 2 operation Between Message and CRC Generator) = 001

So , the message We have to send is 

Message                                                                                   CRC Bits

10011010 001

Remainder will be 101 and padding is required before xor
