Answer:

The correct option is 1.

Explanation:

If a quadratic equation is defined as


ax^2+bx+c=0 .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is


3x^2+11x-4=0 ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is


(-b)/(a)=-(11)/(3)

The sum of roots is
-(11)/(3).

Therefore the correct option is 1.
