Question

(x-2).(x-2)=(x+1).(x+1) SOLUÇAOO

Answer 1

$(x - 2) {}^{2} \times (x + 1) {}^{2} \\ ((x - 2) \times (x + 1)) {}^{2} \\( x {}^{ 2} +x - 2x - 2) {}^{2} \\ (x {}^{2} - x - 2) {}^{2} \\ x {}^{4} + x {}^{2} + 4 - 2x {}^{3} - 4x {}^{2} + 4x \\ x {}^{4} - 3x {}^{2} + 4 - 2x {}^{3} + 4x \\ x {}^{4} - 2x {}^{3} - 3x {}^{2} + 4x + 4$
