Question

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

Answer 1

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

`a^2-b^2 = (a+b)(a-b)\\`

Substitute. A = y, b = 1

`y^2(y+1)(y-1)`

Since x^3 is the same, insert this before y^2

`x^3y^2(y+1)(y-1)\\`

This is the factored form.
