Question

The zeroes of the quadratic polynomial p(x)-ax'+bx+c and the roots of the
quadratic equation ax'+bx+c 0 are
O O
1) Same
O2) Different
O 3) Cannot say
O4) Both (1) and (2)​

Answer 1

Answer:

same

Given that the zeros of the quadratic polynomial ax

2

+bx+c,c



=0 are equal.

=> Value of the discriminant(D) has to be zero.

=>b

2

−4ac=0

=>b

2

=4ac

Since. L.H.S b

2

cannot be negative, thus, R.H.S. can also be never negative.

Therefore, a and c must be of the same sign.
