Answer:
Step-by-step explanation:
hello :
an Degree 3 polynomial with zeros 4, 6, and -2 is :
f(x) = (x-4)(x-6)(x+2)
all polynomial are : a (x-4)(x-6)(x+2) a ≠ 0
Answer:
Step-by-step explanation:
Complex numbers are the numbers represented by the expression = a + bi
Here a = real part of the number
bi = imaginary part
a and b are the real numbers.

[Since,
]

Therefore, its a non real complex number.
2 -
= 
= 
=
This number is a Non real complex number.

= 18i
It's a non real complex number.
3 + 2i
It's a non real complex number.
-289
It's a purely real number.

= 4 + 32
= 36
It's a purely real number.
