More derivatives: The derivative of $$p(x) = (2x-1)^2$$ is $p'(x) =$ .
The derivative of $$q(x) = (2x-1)^3$$ is $q'(x) =$ .
Hint: As we will learn soon, there are more advanced ways of doing this, but you can compute the derivative by expanding the given expressions and writing each of $p$ and $q$ in the standard form of a polynomial.
