#1 Factor completely and if it's a prime, state that it's a prime:
\n" ); document.write( "7x^9 - 28x^8 - 35x^7
\n" ); document.write( "Common Factor: 7x^7
\n" ); document.write( "Ans: 7x^7(x^2 - 4x -5)
\n" ); document.write( "Factor again:
\n" ); document.write( "Ans: 7x^7(x-5)(x+1)
\n" ); document.write( "=========================== \r
\n" ); document.write( "\n" ); document.write( "#2 Same directions
\n" ); document.write( "10s^2 + 4st - 6t^2
\n" ); document.write( "Common Factor: 2
\n" ); document.write( "Ans: 2(5s^2 + 2st - 3t^2)
\n" ); document.write( "Factor again:
\n" ); document.write( "Ans: 2(5s^2 + 5st - 3st - 3t^2)
\n" ); document.write( "2(5s(s+5)-3t(s+t))
\n" ); document.write( "2(s+5)(5s-3t)
\n" ); document.write( "=======================
