here \: is \: your \: answer \: buddy \\  \\ p(x) = 4 {x}^{2}  + 4x + 1 \\   \alpha   +  \beta  =   \frac{ - b}{a}  \\  =  \frac{ - 4}{4} \\  =  - 1 \\  \alpha  \beta  =  \frac{c}{a}  \\  =  \frac{1}{4} \\ now \\  \frac{1}{ \alpha }  +  \frac{1}{ \beta }  =  \frac{ \beta  +  \alpha }{ \alpha  \beta } \\  =  \frac{ - 1}{ \frac{1}{4} } \\  =  - 1 \times 4 \\  =  - 4 \\  \\  \\ hope \: it \: helps \: you \\ pls \: mark \: as \: brainliest
