This is the answer because it is subtracted so that you get the answer
Easy way is to look at the term with the highest exponent. The exponent determines the number of roots. Some might be double roots. THough not all of then will be real. The imaganry ones come in pairs
Examples:
x^4 - 4 roots
x^7 - 7 roots
x^3 - 3 roots
Given:
The function is

The binomial
is a factor of f(x).
To find:
The value of
.
Solution:
If
is a factor of f(x), then
.
It is given that,
is a factor of f(x), then
.
We have,

Substituting x=4, we get




Now,





Therefore, the value of a is 5.
