If p and q are the roots of the equation x² – 3x +2=0, find the value of1/p-1/q. |
|
Answer» Answer: it should be 1 as by calculating roots we GET the values 2 and 1 if we TAKE p=1 and q=2 then p-1=0 which means 1/p-1 will be INFINTE which is not possible so we will take p=2 and q=2 which GIVES us the answer 1/1/1 which is 1 |
