Question

A (a + 1,a -1), B(a² +1,a²-1 and C(a³ +1,a³-1) are given points D(11,9) is the mid point of AB and E (41,39) is the mid point of BC. If F is the mid point of AC then (BF)² is equal to?

Deepak Kumar Shringi · Accepted Answer

mid point of AB=((a+1+a2+1)/2,(a-1+a2-1)/2)=(11,9)a2+a-20=0 ..(i)and also mid point of BC a3+a2-80=0........(ii)from (i) and (ii) a=4now find A,B,C ,F by putting a
