Here is a list of the values of i:
\n" ); document.write( " $\"i=i%3Cbr%3Ei%5E2=-1%3Cbr%3Ei%5E3=-i%3Cbr%3Ei%5E4=1\"$
\n" ); document.write( "After simplifying the squared expression using the FOIL method, we get: $\"1-2i%2Bi%5E2\"$
\n" ); document.write( "Substitute -1 for $\"i%5E2\"$ and the answer is $\"-2i\"$ \n" ); document.write( "

\n" );
