Giải giúp em với ạ
g) \(\frac{x^2-16}{4x-x^2}\)
h) \(\frac{4x^2-4xy}{5x^3-5x^3y}\)
i) \(\frac{5\left(x-y\right)-3\left(y-x\right)}{10\left(x-y\right)}\)
k) \(\frac{x^6+2x^3y^3+y^6}{x^7-xy^6}\)
l) \(\frac{2x^3-7x^2-12x+45}{3x^3-19x^2+33x-9}\)
m) \(\frac{2x+2y+5x+5y}{2x+2y-5x-5y}\)
n) \(\frac{2ax^2-4ax+2a}{5b-5bx^2}\)
o) \(\frac{3x\left(1-x\right)}{2\left(x-1\right)}\)
p) \(\frac{x^2-xy}{3xy-3xy^2}\)
