Question
What is the solution to the given equation?
- -8
- -2
- 2
- 8
The correct answer is: 8
HINT : Expand and solve the equation to get 3 same roots i,e x =8,8,8
Explanation :
If (x-a)(x-b)(x - c )=0 then x= a, b, c are the roots of the equation with degree 3
Here 
Here on comparison a = b = c = 8
Therefore the roots of the equation are x = 8,8,8 Where all 3 roots are the equal.

An inconsistent system is a set of equations for which no solution exists.
One solution of the system is shown as x = y = z = 0. D must be zero for endless solutions (including non-zero ones). There are thus two possible possibilities for k, but there is only one non-zero answer, e.g.: The value of K can be 2 or 0.5.
