Question

9x2y2 -16 factorise

Answer 1

this is the perfect answer of this question.

Answer 2

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).
