Answer 2

Answer:

$\dfrac{d}{dx}\left(x^2+x-2^2\right)=2x+1$

Step-by-step explanation:

$\dfrac{d}{dx}\left(x^2+x-2^2\right)$

$\gray{\mathrm{Apply\:the\:Sum/Difference\:Rule}:\quad \left(f\pm g\right)'=f\:'\pm g'}$

$=\dfrac{d}{dx}\left(x^2\right)+\dfrac{d}{dx}\left(x\right)-\dfrac{d}{dx}\left(2^2\right)$

$\gray{\dfrac{d}{dx}\left(x^2\right)=2x}$

$\gray{\dfrac{d}{dx}\left(x\right)=1}$

$\gray{\dfrac{d}{dx}\left(2^2\right)=0}$

$=2x+1-0$

$\gray{\mathrm{Simplify}}$

$=2x+1$
