Question

6xy+ 9y square ____________​

Answer 1

Step-by-step explanation:

Given expression=6xy+9y2

it can be factorised as 6xy+9y2= 3y( 2x+3y)

Thus factors are 3,y,2x + 3y.

hope its help u

Answer 2

Answer:

36x²y² + 81y² + 108xy²   (Real)

4x² + 12x + 9                   (Simplified)

Step-by-step explanation:

We can solve this question by using identity (x + y)² = x² + y² + 2xy.

(x + y)² = (6xy + 9y)²

Comparing, x = 6xy and y = 9y

=> (6xy + 9y)² = (6xy)² + (9y)² + 2(6xy)(9y)

=> 36x²y² + 81y² + 108xy²         [This is the real expansion.]

Divide the whole equation by 9y².

=> 4x² + 12x + 9                           [This is the simplified expansion]
