Question

if m=x+1/x and n=x , then m²-n²=?​

Answer 1

Step-by-step explanation:

n2

if m x+1x-1and n x-1x +1find m 2+n22 -mn

Answer 2

Answer:

To begin with, please note that m2−n2=(m+n)(m−n) . If we assume m<n , then the only chance to solve (m+n)(m−n)=13 is m−n=1 and m+n=13 (since 13 is a prime number). Which leaves us with m=7 and n=6 .
