Question

if p and q are the zeros of the polynomial f(t) = t^2 - 4t + 3 . find the value of 1/p + 1/q - 2pq

Answer 1

Hi Dear,..........................................Here is ur answer...................................................
f(t)=t^2-4t+3so solve it with hit and trial method to find the zeroes of this polynomial..............so ,          t^2-4t+3=0         t^2-3t-t+3=0         t(t-3)-1(t-3)=0         (t-1)(t-3)=0         so,   given is p and q are zeroes of that polynomial hence let p=1 and q=3so , put value of p and q in given condition   1+1/3-6=-5+1/3={-15+1}/3=-14/3..............................ANSWER@@@we can also take value of p=3 and q=1then ANSWER is not  changed =-14/3HOPE THIS HELPS UH............................@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
