## allie_bear22 2 years ago what is this x^2-49/x^2+7x in simplified form?

1. LaShaun97

x + 7 / x - 7

2. Luigi0210

$\frac{ x^2-49 }{ x^2+7x }=\frac{ (x-7)(x+7) }{ x(x+7) }=\frac{ (x-7) }{ x }$

3. LaShaun97

so i was wrong??

4. allie_bear22

It is D, I used the derivative to locate a max/min and went from there
