Proszę o szybkie rozwiązanie DAJE NAJ za pierwsza odp!

Answer 1

A)(2x^2-4xy)/(x-2y)=2x(x-2y)/(x-2y)=2x

b)(25a^2-16b^2)/(50a^2-80ab+32b^2)=(5a-4b)(5a+4b)/2*(5a+4b)=(5a-4b)/2

c)(x^6+2x^3y^2+y^4)/x^6-y^4)=(x^3+y^2)/(x^3-y^2)(x^3+y^2)=1/(X^3-y^2)

d)(1/2x^2-2/3xy+2/9y^2)/(1/4x^2-1/9y^2)=

=2(1/4x^2-1/3xy+1/9y^2)/(1/2x-1/3y)(1/2x+1/3y)=2(1/2x-1/3y)^2/(1/2x-1/3y)(1/2x+1/3y)

=2/(1/2x+1/3y)
