Paragraph: aligned & a x+b y+c=0 & b x+c y+a=0 & c x+a y+b=0 aligned is a system of linear equation then answer the following questions : Question: If a b c and a+b+c 0 then the system of linear equation have -
Options
- Ainfinite solution all lying on a line
- Bentire xy plane as solution
- Cunique solution
- Dno solution
Correct answer
D. no solution
Step-by-step solution
Consider = | array lll a & b & c b & c & a c & a & b array |= ( a + b + c ) 2 (( a - b )^2+( b - c )^2+( c - a )^2 ) if a b c & a + b + c 0 , then 0 lines are not concurrent & no solution.
