Answer 2

Step-by-step explanation:

9x^2 - 12xy + 4y^2

We can write :-

9x^2 = (3x)^2

12xy = 2×(3x)(2y)

4y^2 = (2y)^2

So, we can write above equation as,

(3x)^2 - 2×(3x)(2y) + (2y)^2

As we know,

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

So, we can also write above equation as,

(3x)^2 - 2×(3x)(2y) + (2y)^2 = ( 3x - 2y )^2

( 3x - 2y )^2 Answer
