$y (x) = 2 x^{2} - 800 x + 90000$

Step 1

Factor $2$ out of $2 x^{2}$ .

$y (x) = 2 (x^{2}) - 800 x + 90000$

Step 2

Factor $2$ out of $- 800 x$ .

$y (x) = 2 (x^{2}) + 2 (- 400 x) + 90000$

Step 3

Factor $2$ out of $90000$ .

$y (x) = 2 x^{2} + 2 (- 400 x) + 2 \cdot 45000$

Step 4

Factor $2$ out of $2 x^{2} + 2 (- 400 x)$ .

$y (x) = 2 (x^{2} - 400 x) + 2 \cdot 45000$

Step 5

Factor $2$ out of $2 (x^{2} - 400 x) + 2 \cdot 45000$ .

$y (x) = 2 (x^{2} - 400 x + 45000)$
