X^2 +2x-3=?

Answer 1

`\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
`x` 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)`
