The sum of the roots of 3x 2 + 11x - 4 = 0 is

-11/3
-4/3
11/3
4/3

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

            .... (1)

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

The given equation is

         ... (2)

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

The sum of roots is

The sum of roots is .

Therefore the correct option is 1.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
