hope this helps u
answer
answer is option (c)
step of explanation
factorization
x^2+7x+10
x^2+2x+5x+10
x(x+2) 5(x+2)
(x+2) (x+5)
x = -2 , - 5
-2,-5 are the zeros of polynomial x^2+7x+10
product of the zero are -2*-5 = 10

x²+ 7x + 10 = 0
alpa( beta) = c/a
= 10/1
alpa× beta = 10
So your answer is 10
x²+ 5x + 2x + 10 = 0
x (x + 5) + 2( x + 5) = 0
x + 2 = 0 x + 5 = 0
x = -2 x = -5
Thank you
