A) \[K>9/8\]
B) \[K<9/8\]
C) \[K<-9/8\]
D) \[K>8/9\]
Correct Answer: B
Solution :
Roots are real and unequal, if \[D={{b}^{2}}-4ac>0\] So, for equation \[k{{x}^{2}}+3x+2=0\] roots will be real and unequal, it \[D={{(3)}^{2}}-4\times 2\times K>0\] i.e., \[9-8K>0\Rightarrow K>\frac{9}{8}\]You need to login to perform this action.
