Answer 2

Răspuns:

Explicație pas cu pas:

a)

(3x - 6)/(3x - 1) : (xy - 2y)/(9x^2 - 1)

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

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

= 3(3x + 1)/y

b)

(2 - x)/(3x + 12) : (x^2 - 4)/(4x + x^2)

= (2 - x)/3(x + 4) : (x - 2)(x + 2)/x(x + 4)

= -(x - 2)/3(x + 4) * x(x + 4)/(x - 2)(x + 2)

= -x/3(x + 2)
