Step 1.1

Apply the distributive property.

$2 y (y + 2) + 3 (y + 2)$

Step 1.2

Apply the distributive property.

$2 y \cdot y + 2 y \cdot 2 + 3 (y + 2)$

Step 1.3

Apply the distributive property.

$2 y \cdot y + 2 y \cdot 2 + 3 y + 3 \cdot 2$

$2 y \cdot y + 2 y \cdot 2 + 3 y + 3 \cdot 2$

Step 2.1.1.1

Move $y$ .

$2 (y \cdot y) + 2 y \cdot 2 + 3 y + 3 \cdot 2$

Step 2.1.1.2

Multiply $y$ by $y$ .

$2 y^{2} + 2 y \cdot 2 + 3 y + 3 \cdot 2$

$2 y^{2} + 2 y \cdot 2 + 3 y + 3 \cdot 2$

Step 2.1.2

Multiply $2$ by $2$ .

$2 y^{2} + 4 y + 3 y + 3 \cdot 2$

Step 2.1.3

Multiply $3$ by $2$ .

$2 y^{2} + 4 y + 3 y + 6$

$2 y^{2} + 4 y + 3 y + 6$

Step 2.2

Add $4 y$ and $3 y$ .

$2 y^{2} + 7 y + 6$

$2 y^{2} + 7 y + 6$
