Question

помогите по Алгебре пожалуйста​

Answer 1

Ответ:

(8x²-8)/(x+3):(2x-2)•x=8x(x-1)/(x+3)•2x(x-1)=4/(x+3)

x=2,5; 4/(2,5+3)=4/5,5=40/55=8/11

x=-3,4; 4/(-3,4+3)=4/(-0,4)=-4/0,4=-40/4=-10

2)(3a-6b):(2a²-8b²)/(a-2b)=3(a-2b)•(a-2b)/2(a-2b)(a+2b)=3(a-2b)/(a+2b)

a=2,6; b=-1,2; 3(2,6+2,4)/(2,6-2,4)=3•5/0,2=15/0,2=150/2=75
