simplify (y^2 - 9) = (y+3)(y-3)
now just cancel out the common terms.
OpenStudy (anonymous):
y^2-9 = (y+3)(y-3)|dw:1353171711050:dw|

what about ?
s^2-2s s-5
--------- divided by -----
s^2+3s-10 s+5
OpenStudy (anonymous):
for the fist numorator you can factor out one s so you get s(s-2)
OpenStudy (shaik0124):
then the equation will b like this just s+5 goes to numerator and s-5 in denominator

s^-2s = s(s-2)
s^2+3s-10 = (s+5)(s-2)
Now do it as I did the first problem...also use this a/b divided by c/d = ad/bc
OpenStudy (anonymous):
for the denominator you need to find to varibles that add to 3 and multilpy to -10 which would be (s-2) and (s+5)
OpenStudy (anonymous):
so is it s-2
-----
s-5 ?

OpenStudy (anonymous):
you can simply this by concelling out some things

OpenStudy (anonymous):
|dw:1353172393823:dw| sorry
OpenStudy (anonymous):
therefor s-2 would cancel and s+5
OpenStudy (anonymous):
im confused . so what is the answer ?
