Solve for x:
\n" ); document.write( "\"3i%282%2B5i%29+=+x%2B6i\" Simplify the right side by multiplying.
\n" ); document.write( "\"6i%2B15i%5E2+=+x%2B6i\" Substitute \"i%5E2+=+-1\"
\n" ); document.write( "\"6i%2B%2815%29%28-1%29+=+x%2B6i\" Subtract 6i from both sides.
\n" ); document.write( "\"-15+=+x\" so...
\n" ); document.write( "\"highlight%28x+=+-15%29\"
\n" ); document.write( "
\n" );
