Algebra.Com's Answer #150975 by ankor@dixie-net.com(22740)![]() ![]() 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( " |
