4x(x-1)-5x(x)=3
\n" ); document.write( "4x^2-4x-5x^2=3
\n" ); document.write( "-x^2-4x-3=0
\n" ); document.write( "x^2+4x-3=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+\" we get:
\n" ); document.write( "x=(-4+-sqrt[4^2-4*1*-3])/281
\n" ); document.write( "x=(-4+-sqrt16+12])/2
\n" ); document.write( "x=(-4+-sqrt28)/2
\n" ); document.write( "x=(-4+-5.29)/2
\n" ); document.write( "x=(-4+5.29)/2
\n" ); document.write( "x=1.29/2
\n" ); document.write( "x=.645 answer.
\n" ); document.write( "x=(-4-5.29)/2
\n" ); document.write( "x=-9.26/2
\n" ); document.write( "x=-4.63 answer.
