Preveď rovnicu kružnice
Preveď rovnicu kružnice:
\( \normalsize x^2+y^2+4x-8y-5=0 \) na rovnicu kružnice v stredovom tvare.
\( \normalsize\left(x+2\right)^2+\left(y-5\right)^2=25 \)
\( \normalsize\left(x+2\right)^2+\left(y-4\right)^2=16 \)
\( \normalsize\left(x+2\right)^2+\left(y-4\right)^2=25 \)
\( \normalsize\left(x+3\right)^2+\left(y-4\right)^2=25 \)
