Answer 2

$\huge{ \underline{ \boxed{ \mathtt{ \purple{4 {x}^{2} - 1}}}}}$

$\huge{ \text{ Solution}}$

First, we need to know an identity:-

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

Now,

$\large{ \sf{ \red{(2x - 1)(2x + 1)}}}$

$\sf{ \large{ \rightarrow{(2x) {}^{2} - (1) {}^{2} }}}$

$\large{ \boxed{ \orange{ \sf{ \rightarrow{4 {x}^{2} - 1}}}}}$

More identities:-

$\sf{ \large{ \blue{(a - b)( {a}^{2} + ab + {b}^{2} )}} = {a}^{3} - {b}^{3} }$

$\sf{ \large{ \blue{(a + b)( {a}^{2} - ab + {b}^{2}) }} = {a}^{3} + {b}^{3} }$
