divide & simplify y^2-25 Ã· y+5 ------ ---- y y+2

OpenStudy (anonymous):

\[(y^2-25)\div y \div (y+5)\div(y+2)\]

OpenStudy (anonymous):

is it this

OpenStudy (anonymous):

(y-5)(y+2)/y

OpenStudy (anonymous):

yes : it would be (y+5)(y-5)(y+2)/y(y+5) y + 5 would be cut and u would get (y-5)(y+2)/y

OpenStudy (anonymous):

i think that

OpenStudy (anonymous):

no yÂ² - 25 Ã· y+5 y y+2

OpenStudy (anonymous):

y^2-25=(y-5)(y+5) (y-5)(y+5)/y Divided by (y+5)/(y+2) is the same as (y-5)(y+5)/y times by (y+2)/(y+5)

OpenStudy (anonymous):

So cancel out the (y+5) and you get \[(y-5)(y+2) \over y\]

OpenStudy (anonymous):

Surgut you can't see the divide line \[(y-5)(y+2) / y\]

OpenStudy (anonymous):

It's in the same sense as dividing by 2 is the same as timesing by a half (which is1/2)
