(D)(x-2)(x+2)
Step-by-step explanation:
As raízes do polinômio são 2 e -2, portanto sua forma fatorada tem que ser (x-x1)(x-x2) se x1=2 e x2=-2. Então:

Step-by-step explanation:
Sina - (cosa)(tanb)/cosa + (sina)(tanb)
sina ≡ (tana)(cosa)
(tana)(cosa) - (cosa)(tanb)/cosa + (tana)(cosa)(tanb)
= cosa(tana - tanb)/cosa(1 + tanatanb)
(cosas cancel out)
= (tana - tanb)/(1 + tanatanb) ≡ tan(a-b)
