$\"%282%2B3i%29%5E3+=+%282%2B3i%29%282%2B3i%29%282%2B3i%29\"$ Multiply the first pair of parentheses.\r
\n" ); document.write( "\n" ); document.write( " $\"%282%2B3i%29%282%2B3i%29+=+%284%2B6i%2B6i%2B9i%5E2%29\"$ But, $\"i%5E2+=+-1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%282%2B3i%29%282%2B3i%29+=+4%2B12i%2B9%28-1%29%29\"$ = $\"4%2B12i-9+=+-5%2B12i\"$ Now multiply this by (2+3i)\r
\n" ); document.write( "\n" ); document.write( " $\"%28-5%2B12i%29%282%2B3i%29+=+-10-15i%2B24i%2B36i%5E2\"$ Simplify.\r
