(A) To find the value of the polynomial $p(x) = 2x^4 - x^2 + 5x - 8$ at $x = -3$,we substitute $-3$ for $x$ in the expression:$p(-3) = 2(-3)^4 - (-3)^2 + 5(-3) - 8$Calculate each term:$(-3)^4 = 81$,so $2(81) = 162$$(-3)^2 = 9$,so $-(9) = -9$$5(-3) = -15$Now,combine these values:$p(-3) = 162 - 9 - 15 - 8$$p(-3) = 153 - 15 - 8$$p(-3) = 138 - 8$$p(-3) = 130$Therefore,the value of the polynomial at $x = -3$ is $130$.

Obtain the value of the following polynomial at the given value of $x$: $p(x) = 2x^4 - x^2 + 5x - 8$ at $x = -3$.
