Answer:
Applying Quotient and power rule. Graphically, for x>0 both curves coincide.
Step-by-step explanation:
1) Firstly, by applying the Quotient and then the Power Rule, we have a subtraction of the argument and, finally the exponent turns to be the coefficient. As it follows:

2) Check the graph below to see this equivalence. to see x>0 they both coincide.

First, simplify the negative addition. 
Follow the order of operations by dividing first. 
Add and subtract from left to right. 

<u><em>Answer: 2(2g+1)</em></u>
Explanation:
Distributive property: a(b+c)=ab+ac
Rewrite the problem down of 4.
2*2=4
2*2g+2
Then you factor out by the common term of 2.
2(2g+1)
Hope this helps!
