Question

which non zero integer is equal to the cube of itself​

Answer 1

Answer:

the answer is 1 and -1.

Explanation:

cube of 1 = 1

cube of -1 = -1

Answer 2

(1) Insufficient. If b<0, then the answer will be no, because it will give an a<0. If b>0, then a will be positive as well. So two different answers.

(2) Insufficient. If c <0, the root, hence, a will be negative, but if c>0, then a will be more than zero too.

(1)+(2) Insufficient. Statements do not provide any information about the relationship between c and b other than if b,c>0 then a>0 and if b,c<0 then a<0. Again, there two possible answers.
