A) \[\frac{-3}{2}\]
B) \[\frac{3}{2}\]
C) \[\frac{2}{3}\]
D) \[\frac{-2}{3}\]
Correct Answer: A
Solution :
We have, \[f(x)=a{{x}^{2}}-6x-6\] |
Now, Product of zeroes \[=\frac{\text{Constant term}}{\text{Coefficient of }{{\text{x}}^{2}}}\] |
\[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,4=\frac{-6}{a}\] (given) |
\[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,a=\frac{-3}{2}\] |
So, option [a] is correct. |
