Help plsss thank youuuu

Answer:

A. (x+5)

Step-by-step explanation:

We are given a quadratic expression $x^2+8x+15$ which we will factorize to see which of the given options is a binomial factor of it.

$x^2+8x+15$

Finding the factors of 15 such that when added, they give a result of 8.

$x^2+3x+5x+15\\\\x(x+3)+5(x+3)\\\\(x+3)(x+5)$

Therefore, we can see that $(x+5)$ is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.
