Question

If root 3 and minus( - )root 3 are the zeroes of x^4- x^3- 5x^2+3x + 36 then find using the relation between the zeroes and the coefficients

Answer 1

Answer:

Let the third root be p.

Since sum of roots =−

coefficient ofx

3

coefficient ofx

2

⇒2+3+p=−

1

−5

⇒5+p=5

⇒p=0

So, the third zero is 0.

Option D is correct.
