Question

if a and b are the zeroes of a quadratic polynomial axsquare +bx+c , then a b =?​

Answer 1

Answer:

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
