Question

If α and β
are the roots of the quadratic
equation ax' +bx+c=0 then α + β
=
​

Answer 1

Answer:

α+β=-b/a

if it is a quadratic equation

Answer 2

Answer:

For given quadratic equation ax² + bx + c = 0

$\alpha = \frac{ - b + \sqrt{ {b}^{2} - 4ac } }{2a} \: \: \: \: \: \: \: \: \beta = \frac{ - b - \sqrt{ {b}^{2} - 4ac } }{2a} \\ \alpha + \beta = \frac{ - 2b}{2a} \\ \alpha + \beta = \frac{ - b}{a}$
