Answer:

It is X + 5

Step-by-step explanation:

Very short on time, but I did a test and that answer was correct, but make sure you check before submitting it in case the question is different

Answer 2

Answer:

Option D. (x + 5)

Step-by-step explanation:

the given expression is $2x^{4}+20x^{3}+50x^{2}$

We have to find the factor of this expression which matches to the options.

$2x^{4}+20x^{3}+50x^{2}$

= $2x^{2}(x^{2}+10x+25)$

= 2x²(x + 5)²

Therefore, the factors of the given expression are 2x² and (x + 5)

Option D. (x + 5) is the correct option.
