Question

divide and simplify. y^2-1/y divided by y+1/y+4

Answer 1

Rewrite \(y^2-1\) using the difference of squares formula:

\[a^2 - b^2 = (a+b)(a-b)\]

Answer 2

what do u mean?

Answer 3

\[y^2 - 1\] is the difference of \(y^2\) and \(1^2=1\)

Answer 4

no, its exactly as i typed

Answer 5

You missunderstand.

\[y^2 - 1 = y^2 - 1^2\]
since \(1 = 1^2\)

Answer 6

And if you have anything like
\[a^2 - b^2\]
You can write it as
\[(a+b)(a-b)\]
