OpenStudy (heyitslizzy13):

just #26-#29

OpenStudy (misty1212):

hey!!

OpenStudy (misty1212):

which one you want to do?

OpenStudy (heyitslizzy13):

OpenStudy (heyitslizzy13):

26-29

OpenStudy (heyitslizzy13):

I have an idea on how to do them but i'm not quite sure

OpenStudy (misty1212):

put a minus sign between them use parentheses

OpenStudy (heyitslizzy13):

okay there

OpenStudy (misty1212):

#27 put a times sign between them, use parentheses

OpenStudy (misty1212):

when you multiply you get \[\frac{3x^2}{x-2}\]

OpenStudy (heyitslizzy13):

ohhh okok

OpenStudy (heyitslizzy13):

that's the answer?

OpenStudy (misty1212):

for #27 yes

OpenStudy (misty1212):

#28 put a fraction bar between them

OpenStudy (heyitslizzy13):

ohh i see and for 26 can i even subtract ._.

OpenStudy (heyitslizzy13):

28 the answer is just x^2 / 2x+2 right

OpenStudy (misty1212):

yup

OpenStudy (heyitslizzy13):

i got 29 too :))))) yay now just 26 i'm not sure about :/

OpenStudy (misty1212):

let me take a look

OpenStudy (heyitslizzy13):

thanks

OpenStudy (misty1212):

\[\frac{3}{x-2}-2x-2\] is good

OpenStudy (heyitslizzy13):

you can't do anything to it?

OpenStudy (misty1212):

you can put them over one denominator if you feel like doing the algebra i would leave it like it is, at least i don't run the risk of messing the algebra up

OpenStudy (heyitslizzy13):

okay thanks a lot!!!!!! :-)
