how do i do this question? i can factor it by an method​

Answer:
The x values are the same, so leave these be. They do not need to be factored. We need to find a way to factor y^4 and y^2
To do this, just factor using the formula for the difference between two squares
[tex]a^2-b^2 = (a+b)(a-b)\\[/tex]
Substitute. A = y, b = 1
[tex]y^2(y+1)(y-1)[/tex]
Since x^3 is the same, insert this before y^2
[tex]x^3y^2(y+1)(y-1)\\[/tex]
This is the factored form.
