simplificati fractiile a)6xy/9xla a2= b)x+3/5x+15= c)x la a2 -4x+4/x la a2 -2x va rog dau 30 p

Răspuns :

a) 6xy/9x^2 = 2y/3x ( am simplificat prin 3x)
b) (x+3)/(5x+15) = (x+3)/5(x+3) = 1/5 (am simplificat prin x+3)
c) (x^2-4x+4)/(x^2-2x) = (x-2)^2/x(x-2) = (x-2)/x (am simplificat prin x-2)
a) Se simplifica cu 3x si devine 2y/3x
b)(x+3)/5(x+3) = 1/5
c)(x-2)^2/x(x-2) = (x-2)/x
