Answer 1

Answer:

-b/a = alpha + beeta

NOT SURE ABOUT THE ANSWER

Answer 2

From Sridhar Acharyya's method, we know that two roots of the general form of a quadratic equation are :

$\frac{ - b + \sqrt{ {b}^{2} - \: 4ac} }{2a}$ , $\frac{ - \: b \: - \: \sqrt{ {b}^{2} - \: 4ac} }{2a}$

Thus, we had applied this useful information and further proceeded in the above picture which is illustrated above by holding one of the roots as $\alpha$ (ALPHA) and the other root as $\beta$ (BETA).
