A) \[8ac=25{{b}^{3}}\]
B) \[6ac=19{{b}^{2}}\]
C) \[40{{b}^{2}}=75ac\]
D) \[8{{b}^{2}}=25ac\]
Correct Answer: C
Solution :
(c): If the roots of \[a{{x}^{2}}+bx+c=0\]are in the ratio m : n, then \[{{\left( m+n \right)}^{2}}a.c=mn{{b}^{2}}.\] Use this concept to solve the problem.You need to login to perform this action.
