all your questions are similar, it means you learn nothing and don't even try to do yourself
if you tried to do yourself you would show us what you have done and where you failed, but yout ONLY post question..

Same process as in the previous problem: 

The coefficient of the x^2 term is 3, and the only integers that multiply to 3 are 1 and 3...

(3x +/- ?)(x +/- ?)

Now there are several ways to factor the constant term 8... 1*8, or 2*4

(3x 1)(x 8)
(3x 8)(x 1)

or

(3x 2)(x 4)
(3x 4)(x 2)

So to get -14 as the coefficient for x we can write

(3x - 2)(x  - 4)

Because -2x + -12x = -14x
Also -2*-4 = +8
and 3x * x = 3x^2

So that's it. :)
