(a)
To find: Write how many complex and how many real zeroes the function has..
The given function has 0 real root and 2 imaginary root.
Given information Given function is
Apply
(b)
To find: Write how many complex and how many real zeroes the function has..
The given function has 3 real root and 0 imaginary root.
Given information Given function is
Substitute x=1 it gives 0 value to the function so it is a root of the above polynomial.
Devide the function by (x-1) it gives
It gives two real root x=1,1
(c)
To find: Write how many complex and how many real zeroes the function has..
The given function has 0 real root and 0 imaginary root.
Given information Given function is
It can not be factorized.
It gives two real root x=1,1
(d)
To find: Write how many complex and how many real zeroes the function has..
The given function has 2 real root and 2 imaginary root.
Given information Given function is
It gives two real root and two imaginary roots.
(e)
To find: Write how many complex and how many real zeroes the function has..
The given function has 2 real root and 2 imaginary root.
Given information Given function is
Substitute x=1 gives 0 value of polynomial so x=1 is one of the roots.
Divide the polynomial by (x-1) gives
Further factorise it gives 1 real root and 2 imaginary roots
It gives two real root and two imaginary roots.
(f)
To find: Write how many complex and how many real zeroes the function has..
The given function has 1 real root and 4 imaginary root.
Given information Given function is
Further factorise it gives 1 real root and 2 imaginary roots
It gives one real root and 4 imaginary roots.
