Question

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

a2 + 7a + 10 = (a + 5)(a +
)

Answer 1

2

Explanation:

Answer 2

(a+2) Is your answer

Explanation:

You could try synthetic division, but it's pretty complicated (not to mention for much harder problems), so you should try factoring this. What two numbers multiply up to 10 and add up to 7? Using trial and error, we would find these two numbers to be 2 and 5. Therefore, it factors into (a+5)(a+2).
