சுருக்குக \frac{x^{3}-y^{3}}{3 x^{2}+9 x y+6 y^{2}} \times \frac{x^{2}+2 x y+y^{2}}{x^{2}-y^{2}}  

தீர்வு:    

கொடுக்கப்பட்டது   = \frac{x^{3}-y^{3}}{3 x^{2}+9 x y+6 y^{2}} \times \frac{x^{2}+2 x y+y^{2}}{x^{2}-y^{2}}

= \frac{(x-y)\left(x^{2}+x y+y^{2}\right)}{3 x^{2}+6 x y+3 x y+6 y^{2}} \times \frac{(x+y)^{2}}{(x+y)(x-y)}

= \frac{\left(x^{2}+x y+y^{2}\right)(x+y)}{3 x(x+2 y)+3 y(x+2 y)}  

= \frac{(x+y)\left(x^{2}+x y+y^{2}\right)}{(3 x+3 y)(x+2 y)}

= \frac{(x+y)\left(x^{2}+x y+y^{2}\right)}{3(x+y)(x+2 y)}  

\frac{\left(x^{2}+x y+y^{2}\right)}{3(x+2 y)}

விடை: \frac{\left(x^{2}+x y+y^{2}\right)}{3(x+2 y)}
