(8a) (b) (a)
(b) (-8a^2) (-b)
(-1) (a^2-2) (b^1-2)
8 divide by -8 is -1, two a at numerator is a^2, then a^2-2
what about b? I have a minus b at the denominator, what would the final b be? a positive or negative? - I took the numerator b which is a positive.
(-1) (a^0) (b^-1)
(-1) (1) (b^-1)
The answer is b^-1.
I think I got my signs wrong and I don't know how to deal with the signs as in the case of b.
Please help to explain how to deal with the signs of b.
