expand (x+2)(x-2) — step-by-step solution

Let's write in expanded form:

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

x \cdot x

+ x \cdot -2

+ 2 x

+ 2 \cdot -2

ℹ

x \cdot x

x^{2}

‖

x \cdot -2

- x \cdot 2

‖

2 \cdot -2

-4

x^{2}

- x \cdot 2

+ 2 x

- 4

ℹ

- x \cdot 2 + 2 x

0

x^{2} + 0 - 4

▷Result: $x^{2} - 4$
