Step 1.2.1

Apply the distributive property.

$u = 1 + x (x - 2) - 2 (x - 2)$

Step 1.2.2

Apply the distributive property.

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

Step 1.2.3

Apply the distributive property.

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

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

Step 1.3.1.1

Multiply $x$ by $x$ .

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

Step 1.3.1.2

Move $- 2$ to the left of $x$ .

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

Step 1.3.1.3

Multiply $- 2$ by $- 2$ .

$u = 1 + x^{2} - 2 x - 2 x + 4$

$u = 1 + x^{2} - 2 x - 2 x + 4$

Step 1.3.2

Subtract $2 x$ from $- 2 x$ .

$u = 1 + x^{2} - 4 x + 4$

$u = 1 + x^{2} - 4 x + 4$

$u = 1 + x^{2} - 4 x + 4$

Step 2

Add $1$ and $4$ .

$u = x^{2} - 4 x + 5$
