Step 1: Consider the quadratic equation ax^2 + bx + c = 0.

Step 2: Now, find two numbers such that their product is equal to ac and sum equals to b. ...

Step 3: Now, split the middle term using these two numbers, ...

Step 4: Take the common factors out and simplify.

6x^2 -4x + 3x - 2 = 0

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

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

1st root:

3x - 2 = 0

3x = 2

x = 2/3

2nd root:

2x+ 1 =0

2x = -1

x = -1/2

Thus, the two roots are 2/3 & -1/2.
