Resol A^2+B^2=O

$$A ^ { 2 } + B ^ { 2 } = O$$

Resoleu A (complex solution)

$$A=-\sqrt{O-B^{2}}$$

$$A=\sqrt{O-B^{2}}$$

Resoleu B (complex solution)

$$B=-\sqrt{O-A^{2}}$$

$$B=\sqrt{O-A^{2}}$$

Resoleu A

$$A=\sqrt{O-B^{2}}$$

$$A=-\sqrt{O-B^{2}}\text{, }O\geq B^{2}$$

Resoleu B

$$B=\sqrt{O-A^{2}}$$

$$B=-\sqrt{O-A^{2}}\text{, }O\geq A^{2}$$
