bardzo prosze o szybkie rozwiąznaie:))

Answer 1

D=R\{-1,2}

Answer 2

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

x =/= -1

x =/= 2

D = R \ {-1, 2}

 

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

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

(x-4)/(x+1) = x/(x-2)

(x-4)(x-2) = x(x+1)

x^2 -2x - 4x + 8 = x^2 + x

-7x = -8  /:(-7)

x = 8/7

x = 1 1/7
