$b (a + b) - a (a - b)$

Step 1

Apply the distributive property.

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

Step 2

Multiply $b$ by $b$ .

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

Step 3

Step 4.1

Move $a$ .

$b a + b^{2} - (a \cdot a) - a (- b)$

Step 4.2

Multiply $a$ by $a$ .

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

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

Step 5

Rewrite using the commutative property of multiplication.

$b a + b^{2} - a^{2} - 1 \cdot - 1 a b$
