A) \[{{x}^{2}}+18x+16=0\]
B) \[{{x}^{2}}-18x+16=0\]
C) \[{{x}^{2}}+18x-16=0\]
D) \[{{x}^{2}}+18x-16=0\]
Correct Answer: B
Solution :
If \[\alpha \] and \[\beta \] are the roots of an equation, then the equation will be Letandbe two numbers whose arithmetic mean is 9 and geometric mean is 4. ...(i) and ...(ii) Required equation is [from Eqs. (i) and (ii)] NOTE If a and to are two numbers, then their arithmetic meanand geometric mean.You need to login to perform this action.
