Solve the equation: 49y - 21sqrt(y) + 2=0\r
\n" ); document.write( "\n" ); document.write( "I have tried squaring the equation to remove the √ but I don't think this is right.
\n" ); document.write( "Sub x for sqrt(y)
\n" ); document.write( "--> 49x^2 - 21x + 2 = 0
\n" ); document.write( "(7x - 1)*(7x - 2) = 0
\n" ); document.write( "Then sub back, and square to get y.
\n" ); document.write( "
\n" );
