And another one.. Factor the given expression. Express your answer so that only positive exponents occur. The answer is: Here is where I am: Factor 1/2 from the exponents.. Multiply the 3/2x(x+4) I don't think that is right..

The answer is: Here is where I am: Factor 1/2 from the exponents.. Multiply the 3/2x(x+4) I don't think that is right.. 1. Split 2. Now you can factor out : 3. Simplify! (The final result is 2 steps ahead)
Cool thanks for helping.
