Hi there,
\n" ); document.write( "x^2 - 64 = 0
\n" ); document.write( "This is referred to as a difference of squares.
\n" ); document.write( "It factorises to:-
\n" ); document.write( "(x - 8)(x + 8)= 0
\n" ); document.write( "x - 8 = 0
\n" ); document.write( "x = 8
\n" ); document.write( "x + 8 = 0
\n" ); document.write( "x = -8
\n" ); document.write( "The two values for x are
\n" ); document.write( "8 and -8
\n" ); document.write( ".........
\n" ); document.write( "To spot another difference of squares
\n" ); document.write( "look for x^2 at the beginning. Followed by
\n" ); document.write( "a negative sign. Then an integer able to
\n" ); document.write( "be square rooted to a whole number.
\n" ); document.write( "Examples:
\n" ); document.write( "x^2 - 169 = 0
\n" ); document.write( "(x - 13)(x + 13)= 0
\n" ); document.write( "4x^2 - 36 = 0
\n" ); document.write( "(2x - 6)(2x + 6) = 0
\n" ); document.write( "Hope this helps:-)
\n" ); document.write( "
\n" );
