Simplify (2x-3)(2x+3)

$(2 x - 3) (2 x + 3)$

Step 1

Expand $(2 x - 3) (2 x + 3)$ using the FOIL Method.

Apply the distributive property.

$2 x (2 x + 3) - 3 (2 x + 3)$

Apply the distributive property.

$2 x (2 x) + 2 x \cdot 3 - 3 (2 x + 3)$

Apply the distributive property.

$2 x (2 x) + 2 x \cdot 3 - 3 (2 x) - 3 \cdot 3$

Step 2

Simplify and combine like terms.

Simplify each term.

Rewrite using the commutative property of multiplication.

$2 \cdot 2 x \cdot x + 2 x \cdot 3 - 3 (2 x) - 3 \cdot 3$

Multiply $x$ by $x$ by adding the exponents.

Move $x$ .

$2 \cdot 2 (x \cdot x) + 2 x \cdot 3 - 3 (2 x) - 3 \cdot 3$

Multiply $x$ by $x$ .

$2 \cdot 2 x^{2} + 2 x \cdot 3 - 3 (2 x) - 3 \cdot 3$

Multiply $2$ by $2$ .

$4 x^{2} + 2 x \cdot 3 - 3 (2 x) - 3 \cdot 3$

Multiply $3$ by $2$ .

$4 x^{2} + 6 x - 3 (2 x) - 3 \cdot 3$

Multiply $2$ by $- 3$ .

$4 x^{2} + 6 x - 6 x - 3 \cdot 3$

Multiply $- 3$ by $3$ .

$4 x^{2} + 6 x - 6 x - 9$

Subtract $6 x$ from $6 x$ .

$4 x^{2} + 0 - 9$

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

$4 x^{2} - 9$
