A) \( \Large t^{2}-2At+G^{2}=0 \) |
B) \( \Large t^{2}-2At-G^{2}=0 \) |
C) \( \Large t^{2}+2At+G^{2}=0 \) |
D) none of these. |
A) \( \Large t^{2}-2At+G^{2}=0 \) |
Let \( \Large \alpha \), \( \Large \beta \) are the root of the required equation,
then \( \Large A = \frac{ \alpha + \beta }{2} => \alpha \beta = 2A \)
and \( \Large G=\sqrt{ \alpha \beta } => \alpha \beta = G^{2} \)
the required equation is \( \Large t^{2}-2At+G^{2}=0 \)
