If the system of linear equations `x=cy+bx`, `y=ax+cz`,`z=bx+ay` has a non trivial solution show that `a^2+b^2+c^2+2abc=1`

Text Solution

Verified by Experts

It is known from solution of equation that a equation will have no trivial solution when the product if matrix is zero
When `x=cy+bx,` thn,`x=1,y=-c,z=-b`
When `y=ax+cz,` then,`x=-a,y=1,x=-c`
When `z=bx+ay`,then, `x=-b,y=-a,z=1`
expanding in matrix form :--
