Derivative of y=ln|2-x-5x^2|: 1+10x/-2+x+5x^2

[2slowtogofast]

y = ln|2-x-5x^2|

when you take the derivitve of somthing like this you can ignore the abs value signs right?

for the ans i got -1-10x / 2-x-5x^2
the answer is 1+10x / -2+x+5x^2

i obviously made some mistake some where because i have the same number just with different signs

The two answers are the same. If the first answer is given by [itex]-a/b[/tex], the second one would be $a/-b$. The negative is just in a different place.[/itex]
