Answer: -2 and -5
Step-by-step explanation:
Let p(x) be x² + 7x + 10
Let's find the roots using splitting the middle term method.
x² + 7x + 10 = 0
x² + 2x + 5x + 10 = 0
x(x + 2) + 5(x + 2) = 0
(x + 2) (x + 5) = 0
So, x = -2 or -5
Therefore, α = -2 and β = -5 are the zeroes of given polynomial.

x + 5 = 0
→ x = –5
x + 2 = 0
→ x = –2
So, –5 and –2 are the zeroes of the given polynomial .
