Algebra

Ok first off, there is a difference between solutions and answers. You should know as you are on this site.

 

2. Can you show your work? I literally plugged those in and they do not seem to satisfy the equation?

 

3. If this is done intentionally, please stop. You are just literally wasting your time going on random questoins and "answering" them. 

1/(a^3 + 7) = -a^3/(a^3 + 7), solve for a

 

The denominators cancel out and you are left with:

 

a^3 = - 1

a = -1
a = (-1)^(1/3)
a = -(-1)^(2/3)
