⭐Hey guys here is your answer⭐
==============================
✔✔The given polynomial ...
x² + 7x + 10
x² + 5x + 2x + 10
x(x + 5) + 2(x + 5)
(x + 5)(x + 2 ) = 0
x + 5 = 0 ......... or......... x + 2 = 0
x = -5 ........ ........or ............x = - 2
✰The relationship between zeroes and coefficient ........
sum of zero = α + β
= (-2) + (-5)
= -7
- 7/1
- (coefficient of x)/(coefficient of x²)
Product of zero ...
= αβ
= (-2) × (-5)
= 10
= 10/1
= (constant term )/(coefficient of x²)
================================
I HOPE IT WILL HELP YOU☺️✌️
thank you✌️

Hey! ! !
Solution :-
x2 + 7x + 10 = (x + 2)(x + 5)
So, the value of x2 + 7x + 10 is zero when x + 2 = 0 or x + 5 = 0
Therefore, the zeroes of x2+ 7x + 10 are –2 and –5.
Sum of zeroes = -7 = –(Coefficient of x) / (Coefficient of x2)
Product of zeroes = 10 = Constant term / Coefficient of x2
