$(x y - 5) ({(x y)}^{2} - 5 x y + 25)$ $(xy-5)((xy)^2-5xy+25)$

Use the formula $a^{3} - b^{3} = (a - b) (a^{2} + a b + b^{2})$ $a^3-b^3=(a-b)(a^2+ab+b^2)$

$(x y - 5) (x^{2} y^{2} + 5 x y + 25)$ $(xy-5)(x^2y^2+5xy+25)$

subtraction of cubes;-

$:.a^3-b^3=(a-b)(a^2+ab+b^2)$

$x^3y^3-125$

$:.=(xy-5)(x^2y^2+5xy+5^2)$

$:.=(xy-5)(x^2y^2+5xy+25)$
