Step-by-step explanation:
3x² + 4y² where x = 2, y = 1, and z = - 3
Here we just need to plug in the given values to their respective variables
3 (2) ² + 4 (1) ² There are no z variables in this equation so plugging in z = - 3 is irrelevant Simplifying our equation we now have: 3 (4) + 4 (1) = 12 + 4 = 16

0 if the original expression is : 3x^2 + 4yz
Step-by-step explanation:
3x^2 + 4yz; I guess this is the original expression.
When x=2, y = 1 z = -3
3x^2 + 4yz = 3 (2) ^2 + 4 * (1) * (-3)
= 3*4 + 4 * (-3) = 12 - 12 = 0
