85 more than a square of a number is the same as 22 times the number. What is the number?

N^2  +  85  =  22N       reaarange  as

 

N^2  - 22N  +  85  =   0               factor as

 

(N  - 17)  (N - 5)  =   0

 

Set each factor to  0 and solve for N  and we  have  two possible  values  for N

 

N=  17     or    N   =  5
