That is a good observation. A simpler approach would be to make common denominator and consider the quadratic polynomial in \(x\), and easily see that the quadratic coefficient and linear coefficient are both 0.

If the L.H.S=f(x) (if none of the a,b,c's are equal to each other) then f(x)=1 for all x in R. So f(x)-1=0 for all x in R. Thus f(x)-1=p(x) is the zero polynomial and not a quadratic.

TopNewesttake L.H.S=f(x), and it is easy to show that f'(x)=0; for all x. ie, f(x)= k = f(-a)= 1, so for all x f(x)=1;

its, not a quadratic equation as such because it has 3 real roots

Log in to reply

yah! u r right its an identity............ just for confusion.

Log in to reply

yes, my answer of -a, -b, -c is not correct as indeed it is an identity function the equation is satisfied for all x belonging to R.

Log in to reply

the roots are -a,-b,-c, assuming a, b, c are distinct real numbers

how did you got the answer? plzzz explain....i'm not able to solve! :|

You got 1 on both sides?
