what are the solution of this equation 2x + 5/2 = 3/x
\n" ); document.write( "------------
\n" ); document.write( "\"2x+%2B+5%2F2+=+3%2Fx\"
\n" ); document.write( "Multiply thru by 2x
\n" ); document.write( "\"4x%5E2+%2B+5x+=+6\"
\n" ); document.write( "\"4x%5E2+%2B+5x+-+6+=+0\"

Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc)
Quadratic equation \"ax%5E2%2Bbx%2Bc=0\" (in our case \"4x%5E2%2B5x%2B-6+=+0\") has the following solutons:
\n" ); document.write( "
\n" ); document.write( " \"x%5B12%5D+=+%28b%2B-sqrt%28+b%5E2-4ac+%29%29%2F2%5Ca\"
\n" ); document.write( "
\n" ); document.write( " For these solutions to exist, the discriminant \"b%5E2-4ac\" should not be a negative number.
\n" ); document.write( "
\n" ); document.write( " First, we need to compute the discriminant \"b%5E2-4ac\": \"b%5E2-4ac=%285%29%5E2-4%2A4%2A-6=121\".
\n" ); document.write( "
\n" ); document.write( " Discriminant d=121 is greater than zero. That means that there are two solutions: \"+x%5B12%5D+=+%28-5%2B-sqrt%28+121+%29%29%2F2%5Ca\".
\n" ); document.write( "
\n" ); document.write( " \"x%5B1%5D+=+%28-%285%29%2Bsqrt%28+121+%29%29%2F2%5C4+=+0.75\"
\n" ); document.write( " \"x%5B2%5D+=+%28-%285%29-sqrt%28+121+%29%29%2F2%5C4+=+-2\"
\n" ); document.write( "
\n" ); document.write( " Quadratic expression \"4x%5E2%2B5x%2B-6\" can be factored:
\n" ); document.write( " \"4x%5E2%2B5x%2B-6+=+%28x-0.75%29%2A%28x--2%29\"
\n" ); document.write( " Again, the answer is: 0.75, -2.\n" ); document.write( "Here's your graph:
