Step 1.2.1

Move $u$ .

$7 (u \cdot u) + 7 u \cdot 4 + 5 (u + 4)$

Step 1.2.2

Multiply $u$ by $u$ .

$7 u^{2} + 7 u \cdot 4 + 5 (u + 4)$

$7 u^{2} + 7 u \cdot 4 + 5 (u + 4)$

Step 1.3

Multiply $4$ by $7$ .

$7 u^{2} + 28 u + 5 (u + 4)$

Step 1.4

Apply the distributive property.

$7 u^{2} + 28 u + 5 u + 5 \cdot 4$

Step 1.5

Multiply $5$ by $4$ .

$7 u^{2} + 28 u + 5 u + 20$

$7 u^{2} + 28 u + 5 u + 20$

Step 2

Add $28 u$ and $5 u$ .

$7 u^{2} + 33 u + 20$
