from now on, please use the notation 6x^2 to show 6x^{2}.

both of your question are ideally set up for 'grouping'

6x2-21xy+8xz-28yz , I will factor the first two and then the last two

= 3x(2x - 7y) + 4z(2x - 7y)

now the 2x-7y is the common factor

= (2x-7y)(3x+4z)

(by expanding our answer we can see that it is correct if we get the original question back, we do!)

now you do the second one, and let me know how you did.
