It.s not correct, but it’s not hard to learn. All you really have to do is multiply both the numerator and the denominator by each of the numerators that are listed in the problem. If you need help just ask, but I’m not going to give you the problem because you can do it! Just ask if you don’t understand.
        
             
        
        
        
The answer is 

first you must multiply or use the FOIL method (First, Outer, Inner, Last)
First you multiply the first terms 

this gives you 3x^2, then you multiple the outer terms

this gives you -21x, then you multiply the inner terms 

that gives you 2x, finally you multiply the last terms 

that gives you 14, now you combine like terms

now you put all the terms together and end up with your solution
