I took -ve common outside so it became the form of 1/√x^2 + a^2

In the answer it does not take -ve common outside so it becomes the form of 1/√a^2 - x^2

[fiery flare]

yea cuz you’re taking sqrt -1 outside

which you can’t do

[fathom spruce]

Ohh you cant?

Shit

[fiery flare]

yea

[fathom spruce]

Uhh might be off topic

But why not

[fiery flare]

square root of negative 1 is not 1

if there’s no square root it’s 1/-1 which is -1

but with the square root is 1/sqrt(-1) which isn’t real

[fathom spruce]

Ohhh I see

Okay

Thanks a lot
