if you have a rational function, set the denominator equal to zero and solve

3. ethompsonn

x = 0 and 3 x = 0 and 2 x = -3 and 3 none of the above

4. ethompsonn

so B?

@snowman97

7. nubeer

set the denominator equal to 0 and then solve. x(x-3) = 0

8. ethompsonn

whaaat?

9. ethompsonn

ooooohhh

10. ethompsonn

so its C? @nubeer

11. nubeer

no.. x(x-3)=0.. it means x = 0 , x-3=0 , x = 3 so 0 and 3

12. ethompsonn

can you help with one more?

13. nubeer

ya sure.

14. ethompsonn

$\frac{ y+5 }{ y^2 +4y - 32 }$

15. ethompsonn

y = -5 and 4 y = 5 and 32 y = 4 and -8 none of the above
