=(3x^3-y^2)^2 [ open it in (a-b)^2 form]
=(3x^3)^2-2.3x^3.y^2+(y^2)^2
=3^2x^3×2-6x^3y^2+y^2×2
=9x^6-6x^3y^2+y^4. ans

Step-by-step explanation:
For this case we assume that for the first square we have the following dimensions:

And we know that:

And the area for the second square would be:

And we know that the sum of areas is 65 so then we have this:

And replacing we got:


We can divide the last expression by 2 and we got:

And we can factorize the last expression like this:

And we have two solutions for
and we got:

Since the length can't be negative we have this:

And
