Algebra.Com's Answer #14366 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Factor to get the following: \n" ); document.write( "[(2x-1)(x-3)]/[(3-x)(x+3)] \n" ); document.write( "Now you have to see the following (3-x)=-(x-3) \n" ); document.write( "Use that fact to write: \n" ); document.write( "[(2x-1)(x-3)]/[-)(x-3)(x+3)] \n" ); document.write( "Cancel the common factor in the numerator and denominator, to get: \n" ); document.write( "[2x-1}/[-(x+3)] \n" ); document.write( "That's as far as you can go in simplifying. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
