THE FIRST STEP FOR THEE TYPE OF EQUATIONS WHERE BOTH TERMS ARE SQUARES IS TO FACTOR EACH SQUARE & THEN MAKE EACH FACTORED TERM A (-) & A (+) OF THE SQUAREROOTS. THUS:
\n" ); document.write( "
\n" ); document.write( "(M^4-9N^4) THE SQUARE ROOT OF M^4 IS M^2 & THE SQUARE ROOT OF 9N^4 IS 3N^2
\n" ); document.write( "SO WE HAVE (M^2-3N^2)(M^2+3N^2)
\n" ); document.write( " \n" ); document.write( "

\n" );
