x− 13/11 = −3/11 
x2 −13/11 + (−13/11)2 = −3/11 + (−13/11)2
(x − 13/11)2 = −3/11 169/121
                   =136/121
x − 13/11 =±√136/121
either x = √136/121 13/11
           =11.66 +13 =2.242
                11      11
Or x = −√136/121 + 13/11
           =−11.66 +13 = 0.1218
                       11
