Question

If -2 , -5 are the zeros of quadratic polynomial x^2+7x+10 then verify the relationship between zeros and the coefficients

Answer 1

Hey buddy here is ur answer !!


alpha= -2
beta = -5

Quadratic equation ;
x^2 + 7x + 10

a = 1
b = 7
c = 10

Here

alpha + beta = -b/a
-2 + (-5) = - 7/1
-2 - 5 = -7
- 7 = - 7
hence LHS = RHS

now

alpha × beta = c/a
-2 × - 5 = 10 / 1
10 = 10

Hence LHS = RHS
