You can put this solution on YOUR website!
I think you mean (4+7i)/(5+5i)
\n" ); document.write( "------------
\n" ); document.write( "There's nothing to solve, it's not an equation.
\n" ); document.write( "You can rationalize the denominator, ie, make it a real number.
\n" ); document.write( "(4+7i)/(5+5i) = (4+7i)/5(1+i)
\n" ); document.write( "Multiply the NUM and DEN by the conjugate of 1+i, which is 1-i
\n" ); document.write( " $\"%284%2B7i%29%2F5%281%2Bi%29+=+%284%2B7i%29%281-i%29%2F%285%281%2Bi%29%281-i%29%29\"$
\n" ); document.write( "= $\"%284%2B7+%2B3i%29%2F%285%2A2%29\"$
\n" ); document.write( "= $\"%2811%2B3i%29%2F10\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
