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

Plug in -1 for x to get:

4(-1)^{2} + 3(-1) + 5 = 4 – 3 + 5 = 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} =24 + 4 – 54 = -26
