Answer: (3x+1)(x+2)
Step-by-step explanation:
You need to know what multiplied by what equals 2 and adds up to 7. You also need to know what multiplied by what equals 3x^2.
So since 3 has no other factor besides 1 we know that (3x+?)(x+?). 2 has no other factor besides 1 as well so you just need to know where to put the 2 and the 1.
(3x+1)(x+2) is the answer you can FOIL it to check it.
3x multiplied by x is 3x^2
3x multiplied by 2 is 6x
1 multiplied by x is just x or 1x
1 multiplied by 2 is 2
Add like terms: 6x+1x is 7x
So your final answer is (3x+1)(x+2)
