Factor.
3g2+ 25g + 8
please put it at (x+b) (x+b) form

(3g + 1)(x + 8)

Step-by-step explanation:

3g2+ 25g + 8; think of FOIL

(3g + ___ ) (g + ___); you know you will get the first term when you multiply 3g and g.  Also you know that the signs will be positive because 25g and 8 are positive.

Now think of the multiples for 8 because it will be the last term; it could be 4*2 or 8*1 and move the options so you get 25g from outers and inners.  You will get this

(3g + 1)(x + 8)
