You can put this solution on YOUR website!
FOLLOWING POLYNOMIALS:
\n" ); document.write( "1. 9 - x^2
\n" ); document.write( "Note this is the difference of square, 9 and x^2 are perfect squares, so we can:
\n" ); document.write( "(3 + x)(3 - x); FOIL this to prove this to yourself
\n" ); document.write( ":
\n" ); document.write( "2.4x^2 + 81 -36
\n" ); document.write( "Do the math on the numbers and you have;
\n" ); document.write( "4x^2 + 45 is about all you can do with this
\n" ); document.write( ":
\n" ); document.write( "3. 4y^2 + 16y + 16
\n" ); document.write( "Note you can factor out 4 here, results
\n" ); document.write( "4(y^2 + 4x + 4)
\n" ); document.write( "This is a perfect square now
\n" ); document.write( "4(y + 2)(y + 2)
\n" ); document.write( "or
\n" ); document.write( "4(y + 2)^2
\n" ); document.write( "
\n" );
