Simplify (x-4)(x-8)

$(x - 4) (x - 8)$

Step 1

Expand $(x - 4) (x - 8)$ using the FOIL Method.

Apply the distributive property.

$x (x - 8) - 4 (x - 8)$

Apply the distributive property.

$x \cdot x + x \cdot - 8 - 4 (x - 8)$

Apply the distributive property.

$x \cdot x + x \cdot - 8 - 4 x - 4 \cdot - 8$

$x \cdot x + x \cdot - 8 - 4 x - 4 \cdot - 8$

Step 2

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot - 8 - 4 x - 4 \cdot - 8$

Move $- 8$ to the left of $x$ .

$x^{2} - 8 \cdot x - 4 x - 4 \cdot - 8$

Multiply $- 4$ by $- 8$ .

$x^{2} - 8 x - 4 x + 32$

$x^{2} - 8 x - 4 x + 32$

Subtract $4 x$ from $- 8 x$ .

$x^{2} - 12 x + 32$

$x^{2} - 12 x + 32$
