Dear Student,
Please find below the solution to the asked query:

We have14x+11+4x+127-1-4x+127=1274x+11+4x+17-1-4x+17Let 4x+1=a=127a1+a7-1-a7We know that 1+An=1+k1A+k2A2+...+knAn=127a1+k1a+k2a2+k3a3+...+k7a7-1-k1a+k2a2-k3a3+...-k7a7=127a1+k1a+k2a2+k3a3+...+k7a7-1+k1a-k2a2+k3a3+...+k7a7=2a27ak1a+k3a3+k5a5+k7a7=126k1+k3a2+k5a4+k7a6=126k1+k34x+12+k54x+14+k74x+16=126k1+k34x+1+k54x+12+k74x+13Highest power of x is 3, hence degree is 3.
