Ayuda por favor es urgente resuelve y simplifica (x-1)(x-2)+(x+3)(x-5)=

Answer 1

Respuesta:

(x-1)(x-2)+(x+3)(x-5)= 2x^2−5x−13

Explicación paso a paso:

(x-1)(x-2)+(x+3)(x-5)=

=(x)(x)+(x)(−2)+(−1)(x)+(−1)(−2)+(x)(x)+(x)(−5)+(3)(x)+(3)(−5)

=x^2+−2x+−x+2+x^2+−5x+3x+−15

Combinar términos comunes:

=x2+−2x+−x+2+x2+−5x+3x+−15

=(x^2+x^2)+(−2x+−x+−5x+3x)+(2+−15)

=2x^2+−5x+−13
