x-3/x^2-16
\n" ); document.write( "IN MATHS CERTAIN OPERATIONS LIKE DIVISION BY ZERO ,LOG OF ZERO OR A NEGATIVE NUMBER ;OR SQUARE ROOT OF A NEGATIVE NUMBER ETC...ARE NOT PERMITTED IN MATHS .HENCE WE SHOULD SEE THAT X DOES NOT TAKE SUCH VALUES WHICH WILL RESULT IN ADOPTING SUCH PROHIBITED PRACTICES.
\n" ); document.write( "HERE IN DENOMINATOR,WE HAVE X^2-16..HENCE IT SHOULD NOT BE ZERO
\n" ); document.write( "THAT IS X^2-16=0..OR X^2=16..OR...X=+4 AND -4 ...THERE IS NO OTHER PROHIBITED AREA .HENCE X SHOULD NOT EQUAL +4 AND -4.
