0=1/(5X+5)-3/(X+1)+7/5
\n" ); document.write( "0=[5(X+1)-3*5(5X+5)+7(5X+5)(X+1)]/[5(5X+5)(X+1)] CROSS MULTIPLYING ELIMINATES THE DENOMINATOR. THUS WE HAVE:
\n" ); document.write( "(5X+5)-15(5X+5)+7(5X^2+10X+5)=0
\n" ); document.write( "5X+5-75X-75+35X^2+70X+35=0
\n" ); document.write( "35X^2+35=0
\n" ); document.write( "35(X^2+1)=0
\n" ); document.write( "X^2+1=0
\n" ); document.write( "USING THE QUADRATIC EQUATION:\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
