Do you want the answer by itself or with steps?

anonymous · Answer

$$\begin{split}
& f(a+1) \
=& (a+1)^2+4(a+1)-3 \
=& (a+1)(a+1)+4(a+1)-3
\end{split}$$

@wio Said I shouldn't I can't decide :P

anonymous · Answer

please give it to me

anonymous · Answer

f(a+1)=(a+1)2+4(a+1)−3
         =(a+1)(a+1)+4(a+1)−3

You can take it from here :)

anonymous · Answer

f(a+1)=(a+1)^2+4(a+1)−3
         =(a+1)(a+1)+4(a+1)−3
         =(a^2 +2a +1) + 4a + 1 -3

K take it from here
