\alpha  +  \beta  =  - 15 \\  \\  \alpha  =  - 7 \\  \\   - 7 +  \beta  =  - 15 \\  \beta  =  - 15 + 7 \\  \beta  =  - 8 \alpha  =  - 7 \\  \beta  =  - 8 \alpha  +  \beta  =   \frac{ - b}{a}  \\  - 15 =    \frac{ - b}{a}  \\  \\ a = 1 \: \:  \:  \: b = 15 \\  \\  \alpha  \beta  =  \frac{c}{a}  \\ 56 =  \frac{c}{a}  \\ c = 56or

\alpha =-15+-7=-22\\\alpha =-22

\alpha +\beta =0\\-22+\beta =0\\\beta =22


amuluibba: plz correct answer select any of these
