Question

Care ma ajuta si pe mine cu acest polinom pls?

Answer 1

Răspuns:

(49/4-a^2/16)+a^2(a^2-4)-

(4a^2-1/4)(a^2/4-1)=

(49/4-a^2/16)+a^2(a^2-4)-

(4a^2-1/4)(a^2/4-1)=

49/4-a^2/16+a^4-4a^2-

(4a^4/4-4a^2-a^2/16+1/4)=

49/4-a^2/16+a^4-4a^2-a^4+4a^2+a^2/16-1/4=

facem reducerile și obtinem

49/4-1/4=(49-1)/4=48/4=12
