Question

Add the following
a 3/5 a4, -7/11 a4​

Answer 1

Answer:D

Step-by-step explanation:

3+(−5)+7+4+(−9)

=14−14

=0

Hence,

x=1 will always be one of the roots.

Now, there are total four roots and we know that complex roots appear in pairs.

However, x=1 is already a real root.

Hence, out of the remaining 3, roots, maximum of 2 can be imaginary.  

Hence, atleast 2 will be real roots always
