Answer 1

its 25 i just took the test

Explanation:

Answer 2

"completes the square," or creates a perfect square trinomial, for x2 + 10x + ___

`x^2 + 10x +____`

To complete the square , we take half of coefficient of middle term and then we square it. Here middle term is 10x.

Coefficient of middle term is 10

Half of 10 is 5

Then square of 5 is 25

We add 25 to get perfect square trinomial

`x^2 + 10x + 25`

`(x+5)(x+5)`

`(x+5)^2`

So 25 is the answer
