How do you solve 25x^4-61x^2+36=0?
\n" ); document.write( "It's a quadratic in x^2
\n" ); document.write( "-----------------------
\n" ); document.write( "You can factor it:
\n" ); document.write( "(25x^2 - 36)*(x^2 - 1) = 0
\n" ); document.write( "x^2 = 1
\n" ); document.write( "x = +1, -1
\n" ); document.write( "-----------
\n" ); document.write( "25x^2 = 36
\n" ); document.write( "x = +6/5, -6/5
\n" ); document.write( " \n" ); document.write( "

\n" );
