Answer 2

${\huge{\boxed{\textit{\red{QU}{\green{ES}{\blue{TI}{\pink{ON}}}}}}}}$

★ Simplify

${x}^{2} - {(1 - x)}^{2}$

${\huge{\boxed{\mathcal{\red{AN}{\green{S}{\blue{WE}{\pink{R}}}}}}}}$

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

here,

$\implies(x + (1 - x))(x - (1 - x) \\ \\ \implies(x + 1 - x)(x - 1 + x ) \\ \\ \implies \: 2x - 1$
