Step 1.1

Apply the distributive property.

$(a (b + c) + b (b + c)) (c + a)$

Step 1.2

Apply the distributive property.

$(a b + a c + b (b + c)) (c + a)$

Step 1.3

Apply the distributive property.

$(a b + a c + b \cdot b + b c) (c + a)$

Step 2

Multiply $b$ by $b$ .

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

Step 3

Expand $(a b + a c + b^{2} + b c) (c + a)$ by multiplying each term in the first expression by each term in the second expression.

$a b c + a b a + a c \cdot c + a c a + b^{2} c + b^{2} a + b c \cdot c + b c a$
