Answer 2

Step-by-step explanation:

a) 9x²=(3x)²

6xy= 2 (3x)(y)

y²= (y)²

= (3x)²+2(3x)(y)+(y)²

as ,(a+b)² = a²+ 2ab+ b²

therefore the answer is (3x+y)² or (3x+y) (3x+y)

b) 4y²=(2y)²

-4y= - 2(2y)(1)

as (a- b)²= a²- 2ab+b²

therefore answer is (2y - 1)² or (2y - 1) (2y - 1)

sorry third question I don't know
