Verified Answer :

The answer is (a+2). Let's find factors of a^2 + 7a + 10. a^2 + 7a + 10 =
a^2 + 5a + 2a + 10 = a a + 5 a + 2 a + 2 5 = (a a + 5 a) +
(2 a + 2 5) = a (a + 5) + 2 (a + 5) = (a + 5) * (a + 2) = (a +
5)(a + 2). Therefore, a^2 + 7a + 10 = (a + 5)(a + 2).

the correct answer is 2

The binomial (a + 5) is a factor of a2 + 7a + 10. What is the other factor?

a2 + 7a + 10 = (a + 5)(a +  ⇒ 2)
