Question

Using (a+b) (a-b) = a²-b² find,
[3/2 m + ⅔ n ] [ 3/2 m - ⅔ ]
​

Answer 1

Answer:

m^2 ×n^2 is the answer

Step-by-step explanation:

Using (a+b) (a-b) = a²-b^2

[3/2 m + ⅔ n ] [ 3/2 m - ⅔ ]

=(3/2m)^2 (2/3n)^2

=(9m^2 /4)(4n^2 /9)

=m^2 ×n^2

Answer 2

Answer:

(3m/2)^2 - (2/3)^2

9m^2/4 - 4/9
