Перетащи элементы

Представь в виде дроби:

• \( \dfrac{-c^{2}+10c+3}{c^{2}-9} \)
• \( \dfrac{-y^{2}+2y-3}{2y(y-3)} \)
• \( \dfrac{b+2}{9b^{2}-4} \)
• \( \dfrac{4d^{2}-13d-2}{3d(d-2)} \)
• \( \dfrac{-c^{2}+c+3}{c^{2}+2} \)
• \( \dfrac{-y^{2}+y-3}{y(y+3)} \)
• \( \dfrac{b+5}{3b^{2}+2} \)
• \( \dfrac{d^{2}+4d-2}{3d(d-2)} \)

а) \( \dfrac{c+1}{c-3} - \dfrac{2c}{c+3} = \) [ ].

б) \( \dfrac{y+1}{2y} - \dfrac{y-2}{y-3} = \) [ ].

в) \( \dfrac{b}{3b-2} - \dfrac{b+1}{3b+2} = \) [ ].

г) \( \dfrac{d+1}{3d} + \dfrac{d-4}{d-2} = \) [ ].
