Step 4.1.10.5.11

Factor $h$ out of $h (- h^{2} - 3 t h - 3 t^{2} + 84 h + 168 t) + h \cdot - 2352$ .

$\frac{0.125 (h (- h^{2} - 3 t h - 3 t^{2} + 84 h + 168 t - 2352))}{h}$

$\frac{0.125 h (- h^{2} - 3 t h - 3 t^{2} + 84 h + 168 t - 2352)}{h}$

Step 4.2.1.1

Cancel the common factor.

$\frac{0.125 h (- h^{2} - 3 t h - 3 t^{2} + 84 h + 168 t - 2352)}{h}$

Step 4.2.1.2

Divide $0.125 (- h^{2} - 3 t h - 3 t^{2} + 84 h + 168 t - 2352)$ by $1$ .

$0.125 (- h^{2} - 3 t h - 3 t^{2} + 84 h + 168 t - 2352)$

Step 4.2.2

Apply the distributive property.

$0.125 (- h^{2}) + 0.125 (- 3 t h) + 0.125 (- 3 t^{2}) + 0.125 (84 h) + 0.125 (168 t) + 0.125 \cdot - 2352$

Step 4.3.1

Multiply $- 1$ by $0.125$ .

$- 0.125 h^{2} + 0.125 (- 3 t h) + 0.125 (- 3 t^{2}) + 0.125 (84 h) + 0.125 (168 t) + 0.125 \cdot - 2352$

Step 4.3.2

Multiply $- 3$ by $0.125$ .

$- 0.125 h^{2} - 0.375 (t h) + 0.125 (- 3 t^{2}) + 0.125 (84 h) + 0.125 (168 t) + 0.125 \cdot - 2352$

Step 4.3.3

Multiply $- 3$ by $0.125$ .

$- 0.125 h^{2} - 0.375 (t h) - 0.375 t^{2} + 0.125 (84 h) + 0.125 (168 t) + 0.125 \cdot - 2352$

Step 4.3.4

Multiply $84$ by $0.125$ .

$- 0.125 h^{2} - 0.375 (t h) - 0.375 t^{2} + 10.5 h + 0.125 (168 t) + 0.125 \cdot - 2352$

Step 4.3.5

Multiply $168$ by $0.125$ .

$- 0.125 h^{2} - 0.375 (t h) - 0.375 t^{2} + 10.5 h + 21 t + 0.125 \cdot - 2352$

Step 4.3.6

Multiply $0.125$ by $- 2352$ .

$- 0.125 h^{2} - 0.375 (t h) - 0.375 t^{2} + 10.5 h + 21 t - 294$

Step 4.4

Move $10.5 h$ .

$- 0.125 h^{2} - 0.375 t h - 0.375 t^{2} + 21 t + 10.5 h - 294$

Step 4.5

Move $- 0.125 h^{2}$ .

$- 0.375 t h - 0.375 t^{2} - 0.125 h^{2} + 21 t + 10.5 h - 294$

Step 4.6

Reorder $- 0.375 t h$ and $- 0.375 t^{2}$ .

$- 0.375 t^{2} - 0.375 t h - 0.125 h^{2} + 21 t + 10.5 h - 294$
