Find the value of the expression $2 xy+3 xz-xyz$, if $x=-1, y=0, z=3$.
Given :
The Given expression is $2xy+3xz-xyz$.
To do :
We have to find the value of the given expression if $x=-1, y=0, z=3$.
Solution :
$2xy+3xz-xyz$.
Substitute, $x=-1, y=0, z=3$ in the expression.
$2xy+3xz-xyz= 2(-1)(0)+3(-1)(3)-(-1)(0)(3)$
$=0-9+0=-9$
The value of $2xy+3xz-xyz$ is $-9$.
