1 answer:
Answer:
All four restrictions apply:
m not= 0
n not= 0
m not= -4n
n not= m/-4
Step-by-step explanation:
For a rational expression, any expression that is a denominator AT ANY POINT in the calculation, must have the appropriate restrictions applied. There are two different expressions, mn and m+4n that we are concerned about here. See image. All four restrictions must be applied.
