7. mar1e0721

i dont get it. well

8. JackSmiley

the quadratic formula is for determining what the variable equals. Is that what you were looking for?

9. mar1e0721

hey i get it. thanks.

10. JackSmiley

|dw:1349587513886:dw| That's the quadratic formula. |dw:1349587548271:dw| This is what you would get, and I don't think that's what you guys are doing now. Am I wrong?

11. JackSmiley

Oh, ok, good on ya' mate.

12. mar1e0721

by the way. 7/5* 18=126. wrong 45

13. JackSmiley

no, i believe 90(7/5) is 126.. do you have a calculatour?

14. JackSmiley

|dw:1349588181810:dw| Although, you were right, I should have written 18, not 45
