Question

write the degree of the polynomial (x+1)(x2-x-x4+1)

Answer 1

Answer:

Degree 5

Step-by-step explanation:

Given : Polynomial $(x+1)(x^2-x-x^4+1)$

To find : Degree of the polynomial

Solution :

To find the degree of polynomial we solve the polynomial so, the variable with highest power is the degree of the polynomial.

$(x+1)(x^2-x-x^4+1)$

$=x(x^2-x-x^4+1)+1(x^2-x-x^4+1)$

$=x^3-x^2-x^5+x+x^2-x-x^4+1$

$=-x^5-x^4+x^3-x+1$

The variable x highest power is 5

Therefore, The polynomial is of degree 5.

Answer 2

Answer:

degree 5 is the right answer
