<u>Solution:</u>
The general form of cubic polynomial is ---- (1)
If we have any cubic polynomial having roots
Sum of roots =
---(2)
From question given that,
--- (3)
On comparing equation (1) and (3), we get a = 1, b = 2, c = -11 and d = -12
Hence the sum of roots using eqn 2 is given as,
=
= -2
Hence the sum of the roots of the polynomial
