Chọn câu sai? (x^3 - 1)/(x^2 - 2x + 1) = (x^2 + x + 1)/(x - 1)

A. $\frac{{\text{x}}^{\text{3}}-\text{1}}{{\text{x}}^{\text{2}}-\text{2x}+\text{1}}=\frac{{\text{x}}^{\text{2}}+\text{x}+\text{1}}{\text{x}-\text{1}}$

B. $\frac{\text{5(x}-\text{y)}-\text{3(y}-\text{x)}}{\text{10(x}-\text{y)}}=\frac{\text{4}}{\text{5}}$

C. $\frac{{\text{x}}^{\text{2}}+\text{4x}+\text{3}}{\text{2x}+\text{6}}=\frac{\text{x}+\text{1}}{\text{2}}$

D. $\frac{{\text{16x}}^{\text{2}}\text{y(x}+{\text{y)}}^{\text{2}}}{\text{12xy(x}+\text{y)}}=\frac{\text{4(x}+\text{y)}}{\text{3}}$
