Answer 1

Respuesta:

Explicación paso a paso:

(a + b)(a + b – c) – (c + a)(c – a – b)+( a + b ) 2 – c 2

=(a)(a)+(a)(b)+(a)(−c)+(b)(a)+(b)(b)+(b)(−c)+a2+ab+bc+−c2+(a)(2)+(b)(2)+−2c

=a2+ab+−ac+ab+b2+−bc+a2+ab+bc+−c2+2a+2b+−2c

=(a2+a2)+(ab+ab+ab)+(−ac)+(b2)+(−bc+bc)+(−c2)+(2a)+(2b)+(−2c)

=2a2+3ab+−ac+b2+−c2+2a+2b+−2c
