Question

using suitable identities
(x-2) (x+2)​

Answer 1

Hello ❤️

(x - 2) (x + 2)

ID: (a + b) (a - b) = a² - b²

= (x)² - (2)²

= x² - 4

Hope this helps u dear ☺️

Answer 2

Given,

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

Given equation is in the form of $(a+b)(a-b)$

This can be written as $(a^{2}-b^{2} )$

Here,

$a=x$, $b=2$

Identity: $(a+b)(a-b)=a^{2}-b^{2}$

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

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

Therefore, here using identity is $(a+b)(a-b)=a^{2}-b^{2}$, and the final solution is $x^{2} -4$.
