Step 1.1

Apply the distributive property.

x (x - 2) - 1 (x - 2)

$x (x - 2) - 1 (x - 2)$

Step 1.2

Apply the distributive property.

x \cdot x + x \cdot - 2 - 1 (x - 2)

$x \cdot x + x \cdot - 2 - 1 (x - 2)$

Step 1.3

Apply the distributive property.

x \cdot x + x \cdot - 2 - 1 x - 1 \cdot - 2

$x \cdot x + x \cdot - 2 - 1 x - 1 \cdot - 2$

x \cdot x + x \cdot - 2 - 1 x - 1 \cdot - 2

$x \cdot x + x \cdot - 2 - 1 x - 1 \cdot - 2$

Step 2.1.1

Multiply

x

$x$ by

x

$x$ .

x^{2} + x \cdot - 2 - 1 x - 1 \cdot - 2

$x^{2} + x \cdot - 2 - 1 x - 1 \cdot - 2$

Step 2.1.2

Move

- 2

$- 2$ to the left of

x

$x$ .

x^{2} - 2 \cdot x - 1 x - 1 \cdot - 2

$x^{2} - 2 \cdot x - 1 x - 1 \cdot - 2$

Step 2.1.3

Rewrite

- 1 x

$- 1 x$ as

$- x$ .

$x^{2} - 2 x - x - 1 \cdot - 2$

Step 2.1.4

Multiply

$- 1$ by

$- 2$ .

$x^{2} - 2 x - x + 2$

$x^{2} - 2 x - x + 2$

Step 2.2

Subtract

$x$ from

$- 2 x$ .

$x^{2} - 3 x + 2$

$x^{2} - 3 x + 2$
