Factor the expression completely over the complex numbers.[tex]y^{4}+40y^{2}+400[/tex ]

The answer is [y² + 20]² because using the "Greatest Common Factor" strategy, you'll have this below:

(y^4 + 20y²) + (20y² + 400)

y²(y² + 20) 20(y² + 20)

[y² + 20][y² + 20] = [y² + 20]²

Sorry it took so long. I was trying to figure out the code for the 4th power exponential. I never take this long to answer any mathematical question. Please forgive me?

Step-by-step explanation:

Consider the given expression

We need to find the factor form of the given expression.

Splitting the middle term, rewrite the middle term as .

Taking out common factors from each parenthesis.

Taking out common factors.

Therefore, the factored form of given expression is .
