A) \[pm=lq\]
B) \[pq=lm\]
C) \[{{p}^{2}}l={{m}^{2}}q\]
D) \[p{{m}^{2}}=l{{q}^{2}}\]
Correct Answer: A
Solution :
[a] : Since both roots of given equations \[a{{x}^{2}}+px+q=0\] and \[b{{x}^{2}}+lx+m=0\]are common. \[\therefore \]\[\frac{a}{b}=\frac{p}{l}=\frac{q}{m}\] Taking\[\frac{p}{l}=\frac{q}{m}\Rightarrow pm=lq\].You need to login to perform this action.
