Question

Find the value of P(2) for P(x)= 2x3-x2-6

Answer 1

P(2)=2.2.2 - 2.2 - 6
=8-4-6= - 2

Answer 2

Answer:

P(2) = 6

Step-by-step explanation:

In a polynomial, you can find out the value of the polynomial P(x)

The given polynomial P(x) = 2x³-x²- 6

P(2) means the value of x=2 so put the value of x on the polynomial to find the value,

P(x) = 2x³-x²- 6

P(2) = 2*(2³)- 2² - 6

       =  16 - 4 - 6

       = 16-10

       = 6

P(2) = 6
