Answer:

20

Step-by-step explanation:

Given,

X = 3

y = -2

Now,

[tex]2 {x}^{2} - y[/tex]

Plugging the value of X and y

[tex]2 \times {(3)}^{2} - ( - 2)[/tex]

Calculate the product

[tex] = 2 \times 9 - ( - 2)[/tex]

[tex] = 18 - ( - 2)[/tex]

[tex] = 18 + 2[/tex]

[tex] = 20[/tex]

Hope this helps...

Good luck on your assignment
