Question

In ax2 + bx + c, if a = 0, then resulting polynomial is
A) Linear polynomial B) Quadratic polynomial
C) Cubic polynomial D) 4th degree polynomial
WITH REASON

Answer 1

Answer:

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

Step-by-step explanation:

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

Answer 2

option A) is correct
