Answer:

Step-by-step explanation:

8-(3x-2)2

Multiply 3 and -2

8-(3(-2)-2)2

You should get 8-(-6-2)2

Subtract -6 from 2. You should get -8

8-(-8)2

Since there are 2 negatives your 8 will become a positive and your subtraction sign will become a addition sign.

8+8*2

You should get 8+16

16 plus 8 equals 24.

Therefore, your answer is 24
