graphically \"y=4x%5E2\" and \"xy=-10\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Like y=x^2 but narrower; and the other equation is a hyperbola.
\n" ); document.write( "You would expect in symbols, to be able to say \"x%284x%5E2%29=-10\",
\n" ); document.write( "\"4x%5E3=-10\"
\n" ); document.write( "\"x%5E3=-10%2F4\"
\n" ); document.write( "\"x%5E3=-5%2F2\"
\n" ); document.write( "\"x=root%283%2C-5%2F2%29=-1.357\" approximately,
\n" ); document.write( "which means \"y=4%28%28-5%2F2%29%5E%281%2F3%29%29%5E2\", \"y=4%28-5%2F2%29%5E%282%2F3%29=7.368\" approximately.\r
