Question

If α, - α are zeroes of the quadratic polynomial , ax

2

+ bx + c = 0 , then value of b is _______ .​

Answer 1

Answer:

Step-by-step explanation:

Correct option is

A

True

If α and β are the zeroes of the quadratic polynomial, then

aα  

2

+bα+c=0  and

aβ  

2

+bβ+c=0

or, aα  

2

+bα − aβ  

2

−bβ=0

Then, α+β=  

a

−b

​ and αβ=  ab c
