APFIVE Verify the derivative of $$f(x)=x^2$$ using the limit definition by ranking the steps. Order the steps from first to last:
A: Write the difference quotient as $$\frac{(a+h)^2 - a^2}{h}$$
B: Expand $$(a+h)^2$$ to obtain $$a^2 + 2*a*h + h^2$$
C: Cancel the $$a^2$$ terms and factor h from the numerator
D: Take the limit as $$h \to 0$$ to conclude that the derivative is $$2*a$$
Write the difference quotient, Cancel common terms and factor h, Expand the binomial, Take the limit as h → 0
