Simplify (x-1)(x-2)

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

Step 1

Expand $(x - 1) (x - 2)$ using the FOIL Method.

Apply the distributive property.

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

Apply the distributive property.

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

Apply the distributive property.

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

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

Step 2

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

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

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

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

Rewrite $- 1 x$ as $- x$ .

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

Multiply $- 1$ by $- 2$ .

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

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

Subtract $x$ from $- 2 x$ .

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

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