Question

value of (x^2-4)-[(x-2)(X+2)]is ?​

Answer 1

$\huge{ \underline{ \boxed{ \mathtt{ \purple{❣Answer \:is = 0}}}}}$

Solution:-

$\sf{ \large{ \red{ {x}^{2} - 4 - [(x - 2)(x + 2)]}}}$

$\sf{ \large{ = > {x}^{2} - 4 - [(x) {}^{2} - (2) {}^{2} ]}}$

$\sf{ \large{ = > {x}^{2} - 4 - ( {x}^{2} - 4)}}$

$\sf{ \large{ = > {x}^{2} - 4 - {x}^{2} + 4}}$

$\sf{ \large{ \boxed{ \orange{ = > 0}}}}$

$\large{ \underline{ \underline{ \sf{ \purple{Used \: Formula}}}}}$

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