Question

x = 2, w = -1, y = 6, z = 4 x²+4w - 2y​

Answer 1

Answer:

-12

Step-by-step explanation:

$x = 2\\ w = -1\\ y = 6\\ z = 4\\x^2+4w-2y$

$(2)^2 +4(-1) -2(6)\\4 -4 -12\\0-12\\\\=-12$

Answer 2

Answer:

4x² + 4w - 2y

4(2)² + 4(-1) - 2(6)

4×4 + (-4) - 12

16 - 4 - 12

12 - 12

0 is the answer
