xa+yb+zc=0bar show that X=y=z=0
Hello candidate,
Here in this question, it is given that the equation containing a, b, and c is equal to zero with variables x, y, and z.
So, pretty clear that the constants cannot be zero all at a time, because then the equation will be meaningless. But, for the same value of of the variables with all equal to zero, the left hand side is equal to the right hand side, so we can say that X=Y=Z=0.
Hope it helps!!
