Answer:

The sum is 1/6

Step-by-step explanation:

This factors into

Factors

(3x - 2)(2x + 1) = 0

First root

3x - 2 = 0

3x = 2

x = 2/3

===============

Second Root

2x + 1 = 0

2x = 1

2x = - 1

x = - 1/2

===============

The two roots are 2/3 and - 1/2

When you add these two together, you get

2/3 - 1/2 = 4/6 - 3/6 = 1/6

The two roots add up to 1/6
