Question

Reduce: (x + 2)(x + 1) + (x - 1)(x – 4)

Answer 1

Vamos a simplificar paso a paso.

(x+2)(x+1)+(x−1)(x−4)

Distribute:

=(x)(x)+(x)(1)+(2)(x)+(2)(1)+(x)(x)+(x)(−4)+(−1)(x)+(−1)(−4)

=x2+x+2x+2+x2+−4x+−x+4

Combinar términos comunes:

=x2+x+2x+2+x2+−4x+−x+4

=(x2+x2)+(x+2x+−4x+−x)+(2+4)

=2x2+−2x+6

solución:

=2x2−2x+6
