Question

Evaluate: P(-1/2) if P(x) = x4 + 3x2 + 2

Answer 1

Plug in -1/2 for all the x's

Answer 2

P(-1/2)=(-1/2)^4 + 3(-1/2)^2 + 2
Work it out and there is your solution.

Answer 3

Would if I knew how

Answer 4

So after simplifying it further, we get 1/16 + 3/4 + 2.
Now we need to find a common denominator, in this case it's 16.
So now the problem becomes 1/16 + 12/16 + 32/16.
Now add: 45/16

Answer 5
