Algebra.Com's Answer #11512 by stanbon!(97)![]() ![]() ![]() You can put this solution on YOUR website! The LCD is (x-3)(3x+4) \n" ); document.write( "Multiply num. and denom. of 1st fraction by (3x+4) to get the following: \n" ); document.write( "x(3x+4)/LCD \n" ); document.write( "Multiply num. and denom. of the 2nd fraction by (x-3) to get the following: \n" ); document.write( "2(x-3)/LCD \n" ); document.write( "Both denominators are now the same so combine the numerators to get the following: \n" ); document.write( "[3x^2+4x +2x-6]/LCD = [3x^2+6x-6]/LCD = 3[x^2+2x-2]/LCD \n" ); document.write( "The numerator is not \"neatly\" factorable now leave it alone. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
