Answer:
x-intercepts are (-6,0 and (2,0)
First option is correct.
Step-by-step explanation:
The given equation is 
For x-intercept, y=f(x)=0. Thus, we have

We can split the middle term as 4x = 6x-2x
Thus, the equation becomes

Now, we make group

Take GCF from each of the group

Factored out the common term

Apply the zero product property,

Solve for x

Thus, x-intercepts are (-6,0 and (2,0)
First option is correct.
