Answer:
Answer 4: (x + 7)
Explanation:
We can say that [tex]x^2 + 9x + 14[/tex] is [tex]x^2 + 7x + 2x + 14[/tex], and if you factor x out of [tex]x^2 + 7x[/tex] and you factor 2 out of [tex]2x + 14[/tex], you get that [tex]x(x + 7) + 2(x + 7)[/tex], and then since you're multiplying x + 7 by x and 2, you can say that this is equal to [tex](x+2)(x+7)[/tex], and one of the factors is x+7, which is answer 4.
