Question

The degree of the polynomial p (x) = x (x-2)² + 4x is

a) 0
b) 3
c) 2
d) 1​

Answer 1

Answer:

Correct option is

A

5

Let P(x)=(x+1)(x2−x−x4+1)

                =x3−x2−x5+x+x2−x−x4+1

                =x3−x5−x4+1

The heighest power of x is 5.  

Thus, the degree of the given polynomial is 5
