Factor the higher degree polynomial
5y^4 + 11y^2 + 2

For this case we must factor the following expression:

We rewrite as:

We make a change of variable:

So, we have:

we rewrite the term of the medium as a sum of two terms whose product is 5 * 2 = 10 and whose sum is 11. Then:

We factor the highest common denominator of each group:

We factor

Returning the change:

its the fourth option
