-2/9y + 5/2z + 53/5
B) 2s-2t+6s+3t-5-4s+3t
4s+4t-5
Todo eso se multiplica por cada fracción. Quedaria:
(2Z) x (5+3Z) x (9Y) x (8-1)/2Z + (2Z) x (5+3Z) x (9Y) x (3-2)/5+3z - (2Z) x (5+3Z) x (9Y) x 2/9Y
Ahora hay que tachar los terminos comunes, asi te quedaria:
(5+3Z) x (9Y) x (8-1) + (2Z) x 9Y) x (3-2) - (2Z) x (5+3Z) x 2
Ahora solo tienes que multiplicar
7 x 9y x (5+3Z) + 1 x 2Z x 9Y - 2 x 2z x (5+3Z)
63Y (5+3Z) + 18YZ - 4Z (5+3Z)
315Y + 189YZ + 18YZ - 20Z + 12Z^2
Reordenando:
12Z^2 + 207YZ +315Y - 20Z
