Question

(m^2 - 16n^2) / [(3m+12n)/mn]

Answer 1

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.
