solution=>

 =( \frac{4}{5} x -  \frac{2}{3} y)( \frac{10}{7}x +  \frac{9}{10}y)( \frac{2}{3}x +  \frac{1}{8} y) \\  \\  = ( \frac{40}{35} x {}^{2} +  \frac{36}{50}xy -  \frac{20}{21}xy -  \frac{18}{30}y {}^{2})  ( \frac{2}{3}x +  \frac{1}{8} y)   \\  \\  =  (\frac{8}{7} x {}^{2} -  \frac{3}{5}y {}^{2} -  \frac{163}{105}xy) ( \frac{2}{3}x +  \frac{1}{8}y  )   \\  \\  =  \frac{16}{21} x {}^{3}   +  \frac{1}{7} x   y {}^{2}  -  \frac{2}{5}  x {}^{2} y -  \frac{3}{40}  y {}^{3}    -  \frac{326}{210} x {}^{2} y -  \frac{163}{840}xy {}^{2}  \\  \\  =  \frac{16}{21}x {}^{3} -  \frac{3}{40} y {}^{3} -  \frac{41}{21}  x {}^{2}y -  \frac{43}{840}  xy {}^{2}
