Give the coefficient of the third term in the expansion of each of the following. \r

\n" ); document.write( "
\r\n" );
document.write( "The kth term of \"%28A+%2B+B%29%5EN\" is \"%28matrix%282%2C1%2CN%2Ck-1%29%29A%5E%28N-k%2B1%29B%5E%28k-1%29\"\r\n" );
document.write( "\r\n" );
document.write( "where \"%28matrix%282%2C1%2CP%2CQ%29%29\"\"%22%22=%22%22\"\"P%21%2F%28Q%21%28P-Q%29%21%29\"\r\n" );
document.write( "\r\n" );
document.write( "So the coefficient is merely \"%28matrix%282%2C1%2CN%2Ck-1%29%29\"\r\n" );
