Answer 2

Answer:

Value of given polynomial is 4

Step-by-step explanation:

Given:

• Polynomial :- 2 + X + 2X² - X³
• Value of X = 2

To finD:

• Value of polynomial at the given value of X

Solution :

We have given polynomial 2 + X + 2X² - X³ where X = 2.

To find the value, we have to substitute the value of X in given polynomial.

Substituting value in given polynomial:

P(X) = 2 + X + 2X² - X³

=> P(2) = 2 + 2 +( 2 ×2²) - 2³

=> P(2) = 4 + 8 - 8

=> P(2) = 12 - 8

=> P (2) = 4

$\large{\boxed{\sf{\green{Hence~ the ~value ~of ~polynomial ~at~ given~ value~ of~ X is ~4}}}}$
