Step-by-step explanation:

 \alpha  \: and \:  \beta  \\  \: are \: the \: zeroes \: of \: the \:  \: polynomial

 {x}^{2}  + 5x + 8

we know that.

 \alpha  +  \beta  =  \frac{ - coefficient \: of \: x}{coefficiet \: of \:  {x}^{2} }

 \alpha  +  \beta  =  \frac{ - b}{a}

 \alpha  +  \beta  =   \frac{ - 5}{1}

 \alpha  +  \beta  =  - 5
