Rút gọn phân thức

a) \(\frac{12x^5y^2}{8x^3y^5}\)

b) \(\frac{x^2+2x+1}{5x^2+5x}\)

Answer 1

a)\(\frac{12x^5y^2}{8x^3y^5}=\frac{3x^2}{2y^3}\)

b)\(\frac{x^2+2x+1}{5x^2+5x}=\frac{\left(x+1\right)^2}{5x\left(x+1\right)}=\frac{x+1}{5x}\)

Answer 2

a/ \(\frac{3x^2}{2y^3}\)

b/ \(\frac{\left(x+1\right)^2}{5x\left(x+1\right)}=\frac{x+1}{5x}\)
