Question

(a+b-1)(a2+1)-a2-1 factorizar​

Answer 1

(a+b−1)(a2+1)−a2−1izar

Distribute:

=(a)(a2)+(a)(1)+(b)(a2)+(b)(1)+(−1)(a2)+(−1)(1)+−a2+−airz

=a3+a+a2b+b+−a2+−1+−a2+−airz

Combinar términos comunes:

=a3+a+a2b+b+−a2+−1+−a2+−airz

=(−airz)+(a3)+(a2b)+(−a2+−a2)+(a)+(b)+(−1)

=−airz+a3+a2b+−2a2+a+b+−1

solución:

=−airz+a3+a2b−2a2+a+b−1
