Question

Find P(2) for the polynomial P(t) = 2 + t + 2t2 - t3​

Answer 1

Answer:

P(2) = 2 + 2 + 2x(2)² - 2³

P(2) = 2 + 2 + 2x(2)² - 2³ = 4 + 8 - 8

P(2) = 2 + 2 + 2x(2)² - 2³ = 4 + 8 - 8 = 4 Ans

Answer 2

The value of P(2) = 4

Given :

The given polynomial P(t) = 2 + t + 2t² - t³

To find :

The value of P(2)

Solution :

Step 1 of 2 :

Write down the given polynomial

The given polynomial is

P(t) = 2 + t + 2t² - t³

Step 2 of 2 :

Find the value P(2)

P(t) = 2 + t + 2t² - t³

Putting t = 2 we get

P(2) = 2 + 2 + 2 × 2² - 2³

⇒ P(2) = 2 + 2 + 8 - 8

⇒ P(2) = 4
