Question

x=-1, y=-2, and z=3 find the value of x²- xy-zx​

Answer 1

Answer:

0 is the answer

Step-by-step explanation:

x²- xy - zx​

put x = -1, y = -2 and z = 3

= (-1)² - (-1)(-2) - (3)(-1)

= - 1 - (2) - (-3)

= -1 -2 + 3

= -3 + 3

= 0

Answer 2

Step-by-step explanation:

${x}^{2} - xy - zx$

$x = - 1$

$y = - 2$

$z = 3$

${ - 1}^{2} - ( - 1 \times ( - 2)) - 3 \times ( - 2)$

$1 - 2 + 6$

$= 5$
