if you're going to use the definition you'll need to find the limit of the difference quotient: \[\large \lim_{h \rightarrow 0} \frac {f(x+h)  f(x)}{h}\] \[\large \lim_{h \rightarrow 0} \frac {[(x+h)^22(x+h)]  [x^22x]}{h}\] \[\large \lim_{h \rightarrow 0} \frac {x^2+2xh+h^22x2h  x^2+2x}{h}\] \[\large \lim_{h \rightarrow 0} \frac {2xh+h^22h}{h}\] \[\large \lim_{h \rightarrow 0} \frac {h(2x+h2)}{h}\] \[\large \lim_{h \rightarrow0} 2x+h2\] \[\large =2x+02 = 2x2\]
