The answer will have the form "m = something"."For what value of m is the following rational equation undefined"

m - 8/m = - 4

the answer must be an equation. What even? I'm so confused!

Suppose I gave you a value for m, and you tried evaluating your expression. In what one case would you say, "I can't do it"? That will be the number they are asking for.

What number can't you divide by?

Typo? Should be `(m-8)/(m-4)`? But then this is an expression, not an equation. And the answer is a value, not an equation either."For what value of m is the following rational equation undefined"

m - 8/m = - 4

Is the given rational equation:"For what value of m is the following rational equation undefined"

m - 8/m = - 4

the answer must be an equation. What even? I'm so confused!

\(\displaystyle m - \frac{8}{m} \ = -4\)

or

\(\displaystyle \frac{m - 8}{m} \ = -4\)

Please clarify!

m^2+ 4m- 8= 0. That is a quadratic equation that can be solved by completing the square or using the quadratic formula.

If, as Subhotosh Kahn suggested, you meant (m- 8)/m= -4 (m- 8/m would be bad notation here but many people make that mistake) then multiplying both sides by m, m- 8= -4m which reduces to 5m= 8.

I doubt this is supposed to be an equation. What does it mean "the following rational equation is undefined"? An equation either has solutions or it doesn't. I've never heard an equation characterized as defined or undefined.
