The sum of the root of 3x^2+11x-4=0

Option (a) is correct.

The sum of roots of given quadratic equation

Step-by-step explanation:

Given quadratic equation

We have to find the sum of roots.

Consider the given quadratic equation

For a given standard quadratic equation , we have

Sum of roots is given by

and product of roots is given by

Thus, for the  given quadratic equation

a = 3 , b = 11 , c = 4

So, the sum of roots is given by

Substitute, we get,

Thus, The sum of roots of given quadratic equation

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
