Question

Find P(-1) for the following polynomial
P (y) =2+y+2y2-y​

Answer 1

Answer:

p(-1)=2+(-1)+2(-1)2-(-1)

-p=1-4

p=3

Answer 2

Answer:

p(-1)=6

Step-by-step explanation:

p(-1) now we will transpose this value to the equation and it will be transported with opposite sign.

so the equation will be:

p(-1)=2+1+1*2*2-1

so,p(-1)=6
