Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
If 2,1,1 are roots of the equation x3-4x2+5x-2=0 Putting 2, 1, 1 in the equation we get: 23+4×22+5×2-2=0; 13+4×12+5×1-2=0; 13+4×12+5×1-2=0; To find the roots of second equation we will subtract 13 from the roots of the first equation, So,…
