How do I find the excluded value for
m^2-8+16/ 5m^2+ m

  • Math - , Thursday, December 5, 2013 at 6:07am

    the expression is undefined when the denominator is zero, because division by zero is undefined.

    5m^2+m = m(5m+1), so it is zero for m = 0 or -1/5

    even ignoring the typo in the numerator.
