x+50/x=10
\n" ); document.write( "(x^2+50)x=10 cross multiply.
\n" ); document.write( "x^2+50=10x
\n" ); document.write( "x^2-10x+50=0
\n" ); document.write( "using the quadratic equation:\"x=%28-b%2B-sqrt%28b%5E2-4%2Aa%2Ac%29%29%2F%282%2Aa%29\" we get:
\n" ); document.write( "x=(10+-sqrt[-10^2-4*1*50])/2*1
\n" ); document.write( "x=(10+-sqrt[100-200])/2
\n" ); document.write( "x=(10+-sqrt-100)/2
\n" ); document.write( "x=(10+-10i)/2
\n" ); document.write( "x=10/2+-10i/2
