Algebra.Com's Answer #740571 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! x+2/5-x divided by x^2-5x-14/x^2-2x-15\r \n" ); document.write( "\n" ); document.write( "---------------- \n" ); document.write( "You can check: \n" ); document.write( "(x+2)/(5-x) divided by (x^2-5x-14)/(x^2-2x-15) \n" ); document.write( "Sub values for x: \n" ); document.write( "Sub 0 \n" ); document.write( "(2/5)/(-14/-15) = -30/-70 = 3/7 \n" ); document.write( "---------- \n" ); document.write( "For the result: \n" ); document.write( "-x+3/x-7 --> -3/7 \n" ); document.write( "So it's not correct. \n" ); document.write( "============= \n" ); document.write( "Using this method to check will easily show if it's not correct, but will sometimes show no difference when it is not correct. \n" ); document.write( " \n" ); document.write( " |
