Evaluate the expression for the given value.

Question

x = -2; y = 3; z = -1

-2x^2y - 3xy^2z - xz =

Answer 1

-2(-2)^2 * 3 - 3(-2)(3)^2 * -1 - (-2)(-1)

-2 * -4 * 3 - 3(-2) * 9 * -1 (-2)(-1)

-2 * -4 * 3 - 6 * 9 * -1 * 2

24 - 108 = -84

Answer 2

x = -2; y = 3; z = -1

-2x^2y - 3xy^2z - xz =

-2(-2)^2(3) - 3(-2)(3)^2(-1) - (-2)(-1)

(-2)(4)(3) -3(-2)((9)(-1) -(-2)(-1)
=
-24 - 54- 2
= -80
