Question

What is the zero of the polynomial f(t)=20a−25bt where a and b are non-zero real numbers?

Answer 1

Answer:

Roots of the given equation are,

=

2a

−(a+b)±

(a+b)

2

−4ab

=

2a

−(a+b)±(a−b)

We get the roots as,

−

a

b

,−1

So, both the roots are real and atleast one negative root.

Hence, B is correct
