Answer 1

Respuesta:

(x +1)(x +2)(x +3)(x + 4)+13 x2 +5x+5

Operaciones:

= (X2+ 3 x + 2 ) ⋅ ( x + 3 ) ⋅ ( x + 4 ) + 13X2+ 5 x + 5 =

= (X3+ 6X2+ 11 x + 6 ) ⋅ ( x + 4 ) + 13X2+ 5 x + 5 =

= (X4+ 10X3+ 35X2+ 50 x + 24 ) + 13X2+ 5 x + 5 =

= (X4+ 10X3+ 48X2+ 50 x + 24 ) + 5 x + 5 =

= (X4+ 10X3+ 48X2+ 55 x + 24 ) + 5 =

=X4+ 10X3+ 48X2+ 55 x + 29

Resultado final es;

X4+ 10X3+ 48X2+ 55 x + 29
