Question

following as a difference of two Squares (3x-2y)(3x+2y)​

Answer 1

Answer:

(9x^2-4y^2)

Step-by-step explanation:

Use the formula

a^2-b^2= (a-b)(a+b)

Converse of this formula is to be applied in this question,

let a=3x

    b=2y

(a-b)(a+b)=a^2-b^2

              =(3x)^2 - (2y)^2

=9x^2-4y^2
