Hi Faatimah A
(3x-2) is a factor
You can use Synthetic Division to divide (3x -2) into 3x3-14x2+26x-12.
(3x3+14x2+26x-12)÷(3x-2)
(3x-2) does divide into your polynomial with no remainder, so it is a factor
I got
x2-4x+6
Please check my math by giving the division a try
There are other methods and I hope this helps
