Step 2.2.1

Multiply $7.4$ by $- 1$ .

$8.3 x^{2} + 0.9 x y + 3.6 - 7.4 x^{2} - (- 1.7 x y) - 1 \cdot 6.4$

Step 2.2.2

Multiply $- 1.7$ by $- 1$ .

$8.3 x^{2} + 0.9 x y + 3.6 - 7.4 x^{2} + 1.7 (x y) - 1 \cdot 6.4$

Step 2.2.3

Multiply $- 1$ by $6.4$ .

$8.3 x^{2} + 0.9 x y + 3.6 - 7.4 x^{2} + 1.7 (x y) - 6.4$

$8.3 x^{2} + 0.9 x y + 3.6 - 7.4 x^{2} + 1.7 x y - 6.4$
