$\implies {\blue {\boxed {\boxed {\purple {\sf { \:(x - 1)(x + 3) }}}}}}$

$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

${x}^(2) + 2x - 3$

$= {x}^(2) + 3x - x - 3$

Taking
as common from first two terms and 1 from last two terms, we have

= x(x + 3) - 1(x + 3)

Taking the factor
(x+3) as common,

= (x - 1)(x + 3)

$\large\mathfrak{{\pmb{\underline{\orange{Mystique35 }}{\orange{❦}}}}}$
