relationship between the zeroes and the coefficients
​

Answer 1

Zeros are -2 and -5 further check attachment....

Answer 2

Step-by-step explanation:

x^2+7x+10=0

x^2+2x+5x+10=0

x(x+2)+5(x+2)=0

(x+5)(x+2)=0

x=-5

x=-2

sum of the zeroes=-b/a

-5-2=-7/1

-7=-7

product of the zeroes=c/a

-5×-2=10/1

10=10
