Find the excluded values of m.

Valery you have to copy the problem exactly as it appears in the original source!!

The expression, if it is a rational, should have division sign.

So, division by zero is not defined.

m^{2} - 8m + 16

————————

5m^{2} + m

5m^{2} + m ≠ 0

m(5m + 1) ≠ 0

**m _{1} ≠ 0 **

5m

_{2}+ 1 ≠ 0

**m**_{2}≠ – 1/5The domain of rational expression are all number out of intervals

**(– ∞, – 1/5) U (– 1/5, 0) U (0, + ∞)**<

**—————**o

**————**o

**—————**>

– ∞ – 1/5 0 + ∞
