Let's evaluate this expression when X is negative <BR>two. To enter the numerator, I'm going to put it in <BR>parentheses. So, parentheses, 3 plus
since my variable as a negative number I'm going <BR>to put that in parentheses as well. So <BR>parentheses
-2
close parentheses, squared,
and close parentheses because I'm finished with <BR>the numerator.
Now, I put the -2 in parentheses, otherwise if I <BR>squared without parentheses it would square the <BR>two not the negative two.
Alright, we're ready to finish. Divided by the <BR>denominator, so, open parentheses
-2 plus one
close parentheses, enter.
