Question

(x + 4) (x2 + 4) + (x+3)(x-4)​

Answer 1

Respuesta:

(x+4)(x2+4)+(x+3)(x−4)

Distribuimos:

=(x)(x²)+(x)(4)+(4)(x²)+(4)(4)+(x)(x)+(x)(−4)+(3)(x)+(3)(−4)

=x³+4x+4x²+16+x²+−4x+3x+−12

Combinar términos comunes:

=x³+4x+4x²+16+x²+−4x+3x+−12

=(x³)+(4x²+x²)+(4x+−4x+3x)+(16+−12)

=x³+5x²+3x+4
