Question summary: Donats els polinomis A(x) = x^2+4·x+4, B(x) = x^2-x-6, C(x) = 2·x^2-2·x, D(x) = -2·x^2-2·x+4, E(x) = -x^2+4, F(x) = -2·x^2+8·x-6. Calculeu [fraction numerator A left parenthesis x right parenthesis over denominator B left parenthesis x right parenthesis end fraction] + [fraction numerator C left parenthesis x right parenthesis over denominator D left parenthesis x right parenthesis end fraction] - [fraction numerator E left parenthesis x right parenthesis over denominator F left parenthesis x right parenthesis end fraction] i simplifiqueu el resultat.
