Factorise ax+ay+az+bx+by+bz .

Factorise ax+ay+az+bx+by+bz.

If the system of equations bx + ay = c, cx + az = b, cy + bz = a has a unique solution, then

If the system of equations bx + ay = c, cx + az = b, cy + bz = a has a unique solution, then

If a !=b , then the system of equation ax + by + bz = 0 bx + ay + bz = 0 and bx + by + az = 0 will have a non-trivial solution, if

If a !=b , then the system of equation ax + by + bz = 0 bx + ay + bz = 0 and bx + by + az = 0 will have a non-trivial solution, if

If a ne b , then the system of equations ax+by+bz=0, bx + ay + bz = 0, bx + by + ax = 0 will have a non– trivial solution if
