Answer 1

`(x + 3)(x + 5)` ✅

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

`{x}^(2) + 8x + 15 \\ ={x}^(2) + 5x + 3x + 15`

Taking
`x` as common from first two terms and 3 from last two terms, we have

`=x(x + 5) + 3(x + 5)`

Taking the factor
`(x+5)` as common,

`= (x + 3)(x + 5)`
