Question

if the zeros of a quadratic polynomial p(X)=ax^2+bc+c , a is not equal to 0are 4,-5 then the roots of the equation is

Answer 1

Answer:

C

c and a have the same sign

Given that the zeros of the quadratic polynomial ax2+bx+c,c=0 are equal.

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

=>b2−4ac=0

=>b2=4ac

Since. L.H.S b2 cannot be negative, thus, R.H.S. can also be never negative.

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