Best ResponseYou've already chosen the best response.0it is the answer but why is it 25/4?

Best ResponseYou've already chosen the best response.0it is \[\frac{25}{4}\] because \[(\frac{5}{2})^2=\frac{25}{4}\]

Best ResponseYou've already chosen the best response.0and it is \[\frac{5}{2}\] because you started with \[x^25x+k\]

Best ResponseYou've already chosen the best response.0Okay so here's what I did: \[p ^{2}  5p + k =0\] coefficient of p = 5 coefficient of p / 2 = 5/2 (coefficient of p/2)^2 = (5/2)^2 = 25.4 \[p ^{2}  5p + 25/4 = k + \left(\begin{matrix}25 \\ 4\end{matrix}\right)\]

Best ResponseYou've already chosen the best response.0= \[(p  5/2)^{2} = 25/4\] = \[p  5/2 = + (\sqrt{25}/\sqrt{4}\]
