P
If \( \mathrm{a}, \mathrm{b}, \mathrm{c} \) represents sides of \( \mathrm{a} \Delta \) then prove that equation \( \mathrm{x}^{2}-\left(\mathrm{a}^{2}+\mathrm{b}^{2}+\mathrm{c}^{2}\right) \mathrm{x}+\mathrm{a}^{2} \mathrm{~b}^{2}+\mathrm{b}^{2} \mathrm{c}^{2}+\mathrm{c}^{2} \mathrm{a}^{2}=0 \) hasimaginary roots.
