Respuesta :
(t-2)(t+1)(t+1)
t^2+t-2t-2(t+1)
t^2-t-2(t+1)
t^3-t^2-2t+t^2-t-2
t^3+-3t-2
t^2+t-2t-2(t+1)
t^2-t-2(t+1)
t^3-t^2-2t+t^2-t-2
t^3+-3t-2
The answer is: t^3-3t-2
(t-2)(t+1)(t+1)= (t-2)(t^2+2t+1) then when you multiply those you get the answer: t^3-3t-2
(t-2)(t+1)(t+1)= (t-2)(t^2+2t+1) then when you multiply those you get the answer: t^3-3t-2
