Given,
Term of factorization is 9x²y²-16
Solution,
For doing the factorization of the given term we can use the formula of a²-b² = (a+b)(a-b). We just need to apply this formula on the given term for factorization.
By applying the formula we get ;
= 9x²y² - 16
= (3xy)² - (4)² [ a²-b² form is created to apply the above mentioned formula. ]
= (3xy+4) (3xy-4)
Hence,the answer of the given factorization is (3xy+4) (3xy-4).
