solve z^2(1-z^2)=16
\n" ); document.write( "---
\n" ); document.write( "Let z^2 = x
\n" ); document.write( "----
\n" ); document.write( "x(1-x) = 16
\n" ); document.write( "x-x^2 = 16
\n" ); document.write( "x^2-x+16 = 0
\n" ); document.write( "x = [1 +- sqrt(1 -4*16)]/2
\n" ); document.write( "---
\n" ); document.write( "x = [1 +- sqrt(-63)]/2
\n" ); document.write( "---
\n" ); document.write( "x = [1 +- isqrt(63)]/2
\n" ); document.write( "----
\n" ); document.write( "z^2 = [1 +- isqrt(63)]/2
\n" ); document.write( "-----------------------------
