What is the value of the polynomial 4x^{2} + 3x + 5 at x = (-1)?

Plug in (-1) for x to find

4(-1)^{2} + 3(-1) + 5

and simplify to 6 .

If x = 2 and y = 3, what is the value of the polynomial 4xy + x^{2} - xy^{3} ?

Substitute 2 for x and 3 for y to get

4(2)(3) + (2)^{2} - (2)(3)^{3}

and simplify to -26.
