Question 33673
38x^2 + 23x + 2

Here you must know how we make factors i.e. splitting of the middle term...(if you might not knew then contact me again and I will explain to you)...we get

= 38x^2 + (19 + 4)x + 2

oepn brackets and we get

= 38x^2 + 19x + 4x + 2

Taking common from first two i.e. 38x^2 + 19x and last two i.e.  4x + 2
variables...we get 

= 19x(x+1) + 2(x+1)

= (19x+2) (x+2)

Hope this will help you
