Uprav v R a urči podmienky
Uprav v \( \R \) a urč podmienky:
\( \large\frac{{k^2+k}}{{kx-ky}} \)
\( \large\frac{k^2+k}{kx-ky}=\frac{k\cdot\left(k+1\right)}{k\cdot\left(x-y\right)}=\frac{k+1}{x-y} \)
\( \normalsize x\neq y,k\neq0 \)
\( \large\frac{k^2+k}{kx-ky}=\frac{k\cdot\left(k+1\right)}{k\cdot\left(x-y\right)}=\frac{k+2}{x-y} \)
\( \normalsize x\neq y,k\neq0 \)
\( \large\frac{k^2+k}{kx-ky}=\frac{k\cdot\left(k+1\right)}{k\cdot\left(x-y\right)}=\frac{k+1}{x+y} \)
\( \normalsize x\neq y,k\neq0 \)
\( \large\frac{k^2+k}{kx-ky}=\frac{k\cdot\left(k+1\right)}{k\cdot\left(x-y\right)}=\frac{k}{x-y} \)
