Answer:

The value will be 56

Explanation:

We have given polynomial
P(x)=2X^4+3X^2+12

We have to find P(-2)

For finding P(-2) we have to put x = -2 in the polynomial

So P(-2) =
2* (-2)^(4)+3* (-2)^2+12=32+12+12=56

So value of P(-2) will be 56

For finding any value we have to just put that value in the polynomial
