Сократите дроби, a) 5x x^2+3x б) x^2-y^2 2x-2y в) 3y y^2-2y г) 3a -3b a^2-b^2

А) 5х/(х^2+3x)=5x/x(x+3)=5/(x+3)
б) (x^2-y^2)/(2x-2y)=(x-y)(x+y)/2(x-y)=(x+y)/2
в) 3y/(y^2-2y)=3y/y(y-2)=3/(y-2)
г) 3(a-b)/(a-b)(a+b)=3/(a+b)

1
5x/x(x+3)=5/9x+3)
2
(x-y)(x+y)/2(x-y)=(x+y)/2
3
3y/y(y-2)=3/(y-2)
4
3(a-b)/(a-b)(a+b)=3/(a+b)
