A) \[{{x}^{2}}+9x+14=0\]
B) \[{{x}^{2}}-9x+14=0\]
C) \[{{x}^{2}}+9x-14=0\]
D) \[{{x}^{2}}-9x-14=0\]
E) None of the above
Correct Answer: B
Solution :
Let the incorrect equation is \[{{x}^{2}}+15x+b=0\]. Since, roots are\[-7\]and\[-2\]. \[\therefore \]Product of roots, \[b=14\] So, correct equation is \[{{x}^{2}}-9x+14=0\]You need to login to perform this action.
