Question

find the product of (a+b+c) (c-a)

Answer 1

Answer:

b+$c^{2}$

Step-by-step explanation:

(a+b+c) (c-a)

= a + b + c × c - a

= (a - a) + b + ($c^{2}$)

= 0 + b + $c^{2}$

=b + $c^{2}$

Answer 2

Answer:

ac - a^2 +bc - ab +c^2 -ac

Step-by-step explanation:

(a+b+c)(c-a) = a(c-a) + b(c-a) + c(c-a)

which equals the answer given.
