Hi, I'm having a little trouble of finding the derivative of something like this:
y=e-2x + (x^2)
So I'm a bit confused.
Like my teacher shows me the derivatove of 4esinx = 4esinx * cosx
There, I tried the same method, doing y' = e2x + (x^2) * e-2x + 2x
Though... in the back of the book, it had 2(x-1)e-2x + (x^2)
I searched up this up, and found that there are rules like this?
But after that... I end up with 2 'e'
I'm not really sure right now.
Can someone explain?
