Answer 1

Respuesta:

solución:

=12x4+5x3−35x2+15x−221

Explicación paso a paso:

Vamos a simplificar paso a paso.

(x+1)(x−2)(4x−1)(3x+5)+11(x−3)(x+7)

Distribute:

=((x+1)(x−2)(4x−1))(3x)+((x+1)(x−2)(4x−1))(5)+(11(x−3))(x)+(11(x−3))(7)

=12x4+−15x3+−21x2+6x+20x3+−25x2+−35x+10+11x2+−33x+77x+−231

Combinar términos comunes:

=12x4+−15x3+−21x2+6x+20x3+−25x2+−35x+10+11x2+−33x+77x+−231

=(12x4)+(−15x3+20x3)+(−21x2+−25x2+11x2)+(6x+−35x+−33x+77x)+(10+−231)

=12x4+5x3+−35x2+15x+−221
