Let `S_r` denotes the sum of rth powers of the roots of `x^4 - x^3 - 7x^2 + x + 6 =` then

Sum of the roots of -7x + 3x^(2) - 1 = 0 is

The sum of the fourth powers of the roots of the equation x^(3) + x + 1 = 0 is

The sum of the roots of the equation 3x^(2) - 7x + 11 = 0

Find the sum of squares of roots of the equation 2x^4 - 8x^3 + 6x^2 - 3=0

Prove the sum of 99t^(th) powers of the roots of the equation x^7-1 = 0 is zero and hence deduce the roots of x^6+x^5+x^4+x^3+x^2+x+1=0
