Answer 1

When w = 8, w² - 4w - 2 = 30.

Explanation:

w² - 4w - 2

Substitute value w = 8.

8² - 4(8) - 2

Square 8.

64 - 4(8) - 2

Multiply -4 and 8.

64 - 32 - 2

Subtract 32 from 64.

32 - 2

Subtract 2 from 32.

30.

Answer 2

`= > {w}^(2) - 4w - 2`

`= > {8}^(2) - 4(8) - 2`

`= > 64 - 32 - 2`

`= > 34`
