You can put this solution on YOUR website!
(x^2-3)^2-43(x^2-3)+42=0
\n" ); document.write( "let u=(x^2-3)
\n" ); document.write( "u^2-43u+42=0
\n" ); document.write( "(u-42)(u-1)=0
\n" ); document.write( "u=1=x^2-3
\n" ); document.write( "x^2=4
\n" ); document.write( "x=±√4=±2
\n" ); document.write( "or
\n" ); document.write( "x=42=x^2-3
\n" ); document.write( "x^2=45
\n" ); document.write( "x=±√45
\n" ); document.write( "solution: x=-√45, -2, 2, √45 \n" ); document.write( "
\n" );
