Ok this is the other problem i dont get(btw i love this forum now) simplify and state restrictions x^2+2x-63/7-x
Originally Posted by Ari Ok this is the other problem i dont get(btw i love this forum now) simplify and state restrictions x^2+2x-63/7-x do you mean ? if so, you should type (x^2 + 2x - 63)/(7 - x)

Originally Posted by Ari Ok this is the other problem i dont get(btw i love this forum now) simplify and state restrictions x^2+2x-63/7-x the restriction is since we have to consider the domain of the first function as well. in the original question, x = 7 makes the denominator zero Originally Posted by Ari yeah thats what i meant, BTW how do you type the way you type? i cant get those fractions and stuff properly like you... i use LaTex. see here
Oh OK so you factor the top and then just cancel them out i see. what about (5m^2+6m-8)/(5m^2-16m-16) * (20m^2+16m)/(4-m^2) OMG I DID IT!
I hope you're not letting me do your homework for you... where's that suspicious smiley? Originally Posted by Ari Oh OK so you factor the top and then just cancel them out i see. what about (5m^2+6m-8)/(5m^2-16m-16) * (20m^2+16m)/(4-m^2) same story here. what do you think the restrictions are? remember, consider the original function as well OMG I DID IT! haha, yes you did not so hard was it?

Thats what i was planning on doing but i got an email saying you posted so im reading that ATM thanks!
m doesnt = 4 or -2 <---is that right? and im stuck here, do i cancel or recipricate and muiltyply?
Originally Posted by Ari m doesnt = 4 or -2 <---is that right? what about the (2 - x) and the (5m + 4) in the denominators of the original fractions and im stuck here, do i cancel or recipricate and muiltyply? multiply the first fraction by the reciprocal of the second fraction and see if anything cancels. if not, just multiply
so m doesnt = 2 but how do i do the (5m-4)? did i cancel the right stuff?
Originally Posted by Ari so m doesnt = 2 but how do i do the (5m-4)? set 5m + 4 = 0, solve for m did i cancel the right stuff? no
m doesnt = -4/5 then what am i supposed to cancel?
