using the foil method multiply out the question the first of term a to the two terms in b, and the second term in a by the 2 terms in b.\r
\n" ); document.write( "\n" ); document.write( "so you get\r
\n" ); document.write( "\n" ); document.write( "(5)(3)+(5)(-7i)+(4i)(3)+(4i)(7i)
\n" ); document.write( "or
\n" ); document.write( "15-35i+12i+28i^2\r
\n" ); document.write( "\n" ); document.write( "combine like terms\r
\n" ); document.write( "\n" ); document.write( "28i^2-(23i)+15
\n" ); document.write( "
\n" );
