Step 1

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

Tap for more steps...

Step 1.1

Apply the distributive property.

$y (y - 2) - 2 (y - 2)$

Step 1.2

Apply the distributive property.

$y \cdot y + y \cdot - 2 - 2 (y - 2)$

Step 1.3

Apply the distributive property.

$y \cdot y + y \cdot - 2 - 2 y - 2 \cdot - 2$

$y \cdot y + y \cdot - 2 - 2 y - 2 \cdot - 2$

Step 2

Simplify and combine like terms.

Step 2.1.1

Multiply $y$ by $y$ .

$y^{2} + y \cdot - 2 - 2 y - 2 \cdot - 2$

Step 2.1.2

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

$y^{2} - 2 \cdot y - 2 y - 2 \cdot - 2$

Step 2.1.3

Multiply $- 2$ by $- 2$ .

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

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

Step 2.2

Subtract $2 y$ from $- 2 y$ .

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

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