The commutative property states that you can invert the order of the terms of a sum:
![a+b=b+a](https://tex.z-dn.net/?f=a%2Bb%3Db%2Ba)
So, if you start with
![\dfrac{1}{3}+\dfrac{2}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3%7D%2B%5Cdfrac%7B2%7D%7B5%7D)
Applying the commutative property you'll get
![\dfrac{2}{5}+\dfrac{1}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%2B%5Cdfrac%7B1%7D%7B3%7D)
Answer: x=0 or x= plus or minus 2
Step-by-step explanation:
g(x)=x^4-8x^2+7
Critical numbers are the numbers where the first derivative is zero
g'(x)=4x^3-16x+0
=4x^3-16x
g'(x)=0
Implies
4x^3-16x=0
4x(x^2-4)=0
4x=0 OR x^2-4=0
x=0 or x^2=4
x=0 or x= plus or minus 2
