Помогите решить! Нужно сократить.[tex] \frac{ x^{3} - xy^{2} }{x^{2} -xy } [/tex]; [tex] \frac{2z^{2} - 8 }{6z^{2} + 12z } [/tex]; [tex] \frac{x^{3} - y^{3} }{x^{2} - y^{2} } [/tex]; [tex] \frac{x^{3} - y^{3} }{(x-y)^{2}} [/tex]. Дальше разложить на множители числитель и знаменатель дроби и сократите её. [tex] \frac{ax-ay}{ax+bx-ay-by} [/tex]; [tex] \frac{mn-pq+mq-pn}{pq+pn } [/tex].

tutta13 1) $= \frac{x( x^{2} - y^{2} )}{x(x-y)} = \frac{x(x-y)(x+y)}{x(x-y)}=x+y$
2) $= \frac{2(z^{2}-4)}{6z(z+2)}= \frac{2(z-2)(z+2)}{6z(z+2)}= \frac{z-2}{3z}$
3) $= \frac{(x-y)(x^2+xy+y^2)}{(x-y)(x+y)}= \frac{x^2+xy+y^2}{x+y}$
4) $= \frac{(x-y)(x^2+y+y^2)}{(x-y)^2}= \frac{x^2+y+y^2}{x-y}$

1) $= \frac{a(x-y)}{a(x-y)+b(x-y)}= \frac{a(x-y)}{(a+b)(x-y)}= \frac{a}{a+b}$
2) $= \frac{m(n+q)-p(q+n)}{p(q+n)}= \frac{(m-p)(q+n)}{p(q+n)}= \frac{m-p}{p}$
