$0.000131 h^{2} + 0.000001 (393 t h) + 0.000001 (393 t^{2}) + 0.000001 (- 8500 h) + 0.000001 (- 17000 t) + 0.000001 \cdot 2010000$

Step 4.3.2

Multiply $393$ by $0.000001$ .

$0.000131 h^{2} + 0.000393 (t h) + 0.000001 (393 t^{2}) + 0.000001 (- 8500 h) + 0.000001 (- 17000 t) + 0.000001 \cdot 2010000$

Step 4.3.3

Multiply $393$ by $0.000001$ .

$0.000131 h^{2} + 0.000393 (t h) + 0.000393 t^{2} + 0.000001 (- 8500 h) + 0.000001 (- 17000 t) + 0.000001 \cdot 2010000$

Step 4.3.4

Multiply $- 8500$ by $0.000001$ .

$0.000131 h^{2} + 0.000393 (t h) + 0.000393 t^{2} - 0.0085 h + 0.000001 (- 17000 t) + 0.000001 \cdot 2010000$

Step 4.3.5

Multiply $- 17000$ by $0.000001$ .

$0.000131 h^{2} + 0.000393 (t h) + 0.000393 t^{2} - 0.0085 h - 0.017 t + 0.000001 \cdot 2010000$

Step 4.3.6

Multiply $0.000001$ by $2010000$ .

$0.000131 h^{2} + 0.000393 (t h) + 0.000393 t^{2} - 0.0085 h - 0.017 t + 2.01$

Step 4.4

Move $- 0.0085 h$ .

$0.000131 h^{2} + 0.000393 t h + 0.000393 t^{2} - 0.017 t - 0.0085 h + 2.01$

Step 4.5

Move $0.000131 h^{2}$ .

$0.000393 t h + 0.000393 t^{2} + 0.000131 h^{2} - 0.017 t - 0.0085 h + 2.01$

Step 4.6

Reorder $0.000393 t h$ and $0.000393 t^{2}$ .

$0.000393 t^{2} + 0.000393 t h + 0.000131 h^{2} - 0.017 t - 0.0085 h + 2.01$
