Question

3a(a+b+c)- 2a(a+b+c) from(-a+b+c)​

Answer 1

Step-by-step explanation:

• (-a+b+c)-( 3a(a+b+c)-2a(a+b+c)

-a+b+c - (( 3a^2+3ab+3ac)-(2a^2+2ab+2ac))

-a+b+c- (3a^2-2a^2+3ab+2ab+3ac+2ac)

-a+b+c- (a^2+5ab+5ac)

-a(a^2+5ab+5ac)+b(a^2+5ab+5ac)+c(a^2+5ab+5ac)

(-a^3-5a^2b-5a^2c)+(ba^2+5ab^2+5abc)+(ca^2+5abc+5ac^2)
