1.

2. Factorise the following expressions.36x²y² - 64​

Answer»

Answer:

36x²y²-64

(6XY)² - (8)²

to factorize this , we NEED to use the formula - a²-b² =(a+b)(a-b)

a=6xy

b=8

factors = (6xy+8 ) (6xy-8)

             = 2(3xy+4) * 2(3xy-4)

              = 4*(3xy+4)*(3xy-4)

Step-by-step explanation:

factors are = 4

                    (3xy+4)

                    (3xy-4)
