Hello!

We are going to evaluate the expression with our given x-value for question 2.

We know that our expression is: x^4 + 5x^3 - 3x^2 + 11x - 6

We also know that our x-value = 3

We will simply plug in "3" to "x" in our expression and solve.

Solve:

x^4 + 5x^3 - 3x^2 + 11x - 6

Plug in 3 to x:

(3)^4 + 5(3)^3 - 3(3)^2 + 11(3) - 6

Simplify:

(3)^4 + 5(3)^3 - 3(3)^2 + 11(3) - 6

81 + 5(3)^3 - 3(3)^2 + 11(3) - 6

81 + 135 - 3(3)^2 + 11(3) - 6

81 + 135 - 27 + 33 - 6

216 - 27 + 33 - 6

189 + 33 - 6

222 - 6 = 216

Therefore, our final answer would be 216.

Answer:

216
