Write in Standard Form (x-2)^2-4

${(x - 2)}^{2} - 4$

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c$

Simplify each term.

Rewrite ${(x - 2)}^{2}$ as $(x - 2) (x - 2)$ .

$(x - 2) (x - 2) - 4$

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

Apply the distributive property.

$x (x - 2) - 2 (x - 2) - 4$

Apply the distributive property.

$x \cdot x + x \cdot - 2 - 2 (x - 2) - 4$

Apply the distributive property.

$x \cdot x + x \cdot - 2 - 2 x - 2 \cdot - 2 - 4$

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

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

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

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

Multiply $- 2$ by $- 2$ .

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

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

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

Combine the opposite terms in $x^{2} - 4 x + 4 - 4$ .

Subtract $4$ from $4$ .

$x^{2} - 4 x + 0$

Add $x^{2} - 4 x$ and $0$ .

$x^{2} - 4 x$
