## Anguyennn one year ago Hello I need help with a quadratic formula

1. Anguyennn

2. Anguyennn

It asks what the smaller root is and what the larger root is! And I am not sure what it means by that.

3. anonymous

Start by simplifying under the radical. Once you do, the two solutions come from the ± sign. Add to get one and subtract for the other

4. Anguyennn

yes but....

5. myininaya

have you approximated both values yet?

6. myininaya

$x=\frac{-(-5) + \sqrt{(-5)^2-4(-2)(-2)}}{2(-2)} \approx ? \\ x=\frac{-(-5)- \sqrt{(-5)^2-4(-2)(-2)}}{2(-2)} \approx ?$

7. Anguyennn

wait hold on lemme do it ok

8. myininaya

actually these both come out very nicely no need for approximations

9. Anguyennn

I dont understand what it asks by the smaller and larger root

10. myininaya

well can you tell me what you got from the above computations ?

11. Anguyennn

I got -2 for one of them

12. Anguyennn

and for the other i got -0.5

13. myininaya

ok so you don't know which is larger of the two?

14. Anguyennn

-0.5

15. myininaya

right and the smaller one is -2

16. Anguyennn

ohhh thats it?

17. myininaya

yep

18. Anguyennn

wow thank you!!!!

19. Anguyennn

gave you a metal :)

20. myininaya

thank you

21. Anguyennn

see ya!
