Your Solution:

(a³ - b² - c) - (a³ + b² - c)

= a³ - b² - c - a³ - b² + c

= a³ - a³ - b² - b² - c + c

= -2b²

I hope you got it.

Answer:

First we change side

a³-b²-c - a³+b²-c

Then we change sign of the right hand expression

a³-b²-c -(+a³-b²+c)

=a³-b²-c -a³-b²+c)

Now just keep them in same expression so we can minus it

=a³-a³-b²-b²-c+c

= -2b²

Not writing the c one because it's 0

Hence, 0 don't have negative sign or positive

0dont have a sign
