You can put this solution on YOUR website!
2x-3/x+4 = x-3/x-4
\n" ); document.write( "Multiply the whole equation by (x-4) (x+4). OR Cross-multiply.\r
\n" ); document.write( "\n" ); document.write( "(2x-3) (x-4) = (x-3) (x+4) One of the two terms you are multiplying by cancels the denominator.\r
\n" ); document.write( "\n" ); document.write( "Now distribute.\r
\n" ); document.write( "\n" ); document.write( "2x^2-11x+12= x^2+x-12\r
\n" ); document.write( "\n" ); document.write( "x^2 -12x +24=0
\n" ); document.write( "(1/2) [12 +/- sqrt (144-96)]\r
\n" ); document.write( "\n" ); document.write( "(1/2) [12 +/- 4 sqrt (3)]\r
\n" ); document.write( "\n" ); document.write( "6+ 2sqrt (3) = 9.464
\n" ); document.write( "6-2 sqrt (3)\r
\n" ); document.write( "\n" ); document.write( "Substitute the numerical value in\r
\n" ); document.write( "\n" ); document.write( "(15.928/13.464) = 6.464/5.464\r
\n" ); document.write( "\n" ); document.write( "1.1830 ; 1.1830\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
