2(x-1)=2-x

2x-2=2-x

2x+x=2+2

3x=4

x=4/3

la solution de cette equations est 4/3

$(3x + 1) {}^{2} - x {}^{2} = 0 \\ (3x + 1 - x)(3x + 1 + x) = 0 \\ (2x + 1)(4x + 1) = 0 \\ 2x + 1 = 0 \: \: ou \: 4x + 1 = 0 \\ 2x = - 1 \: ou \: 4x = - 1 \\ x = - \frac{1}{2} \: ou \: x = - \frac{1}{4} \\ - \frac{1}{2} \: et \: - \frac{1}{4} \: sont \: solutions \: de \: cette \: equation \:$
