Question

find the product of (x+2)(x-2) please help me

Answer 1

Here is the answer

We know that,

$\tt{(a + b)(a - b) = {a}^{2} - b {}^{2}}$

Thus,

According to your question,

Let a be x and b be 2.

Therefore,

$\tt{(x + 2)(x - 2) = x {}^{2} - 2 {}^{2}}$

$\tt{ = x {}^{2} - 4}$


Thus,

The value of ( x + 2) ( x - 2) is x^2 - 4.
