- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Given equations, 3x-2y+z=0 λx-14y+15z=0 x+2y-3z=0 If homogeneous system of linear equations has non trivial solution then determinant is zero. Therefore we can say that, ∆=0 ⇒ 3-21λ-14512-3=0 ⇒3(42-30)+2(-3λ-15)+1(2λ+14)=0…
