factorise : 9x²y² -25

Answer 1

Answer:

Here is the answer

Step-by-step explanation:

Equation =>

=>(9x^2y^2-25)

=>[(3xy)^2-(5)^2].

=>(3xy+5)(3xy-5) [a^2-b^2=(a+b)(a-b).

HOPE IT HELPS.

Answer 2

Answer:

9x²y² - 25

= (3xy)² - (5)²

the formula is a² - b² = (a+b) (a-b)

(3xy + 5) ( 3xy - 5) is the answer......
