factor:

1. $x^{2}+8x + 15$

Explanation:

Step1: Find pair of factors for 15

Look for two numbers that multiply to $15$ and add to $8$: $3$ and $5$ (since $3 \times 5 = 15$ and $3 + 5 = 8$).

Step2: Rewrite as factored binomials

Express the quadratic as a product of two linear binomials using the found numbers.
