Question

Find the derivative of 1/x-1/x^2

Answer 1

Re-write with negative exponents and it'll be a lot easier than the quotient rule.

Answer 2

How do I do that? @NoelGreco

Answer 3

\(\bf \cfrac{1}{a^{\color{red} n}}\implies a^{-{\color{red} n}}\qquad thus
\\ \quad \\
\cfrac{d}{dx}\left[\cfrac{1}{x}-\cfrac{1}{x^2}\right]\implies \cfrac{d}{dx}[x^{-1}-x^{-2}]\)

Answer 4

Ohhh okay

Answer 5

So would it be -x^-2+2x^-3
