Question

Help me to get answer​

Answer 1

Answer:

______________________________

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

$\alpha \times \beta = \frac{c}{a}$

For finding

$\alpha - \beta$

We know that

$( { \alpha - \beta })^{2} = ( { \alpha + \beta })^{2} - 4 \alpha \beta$

By substituting the values from above

We get

$( { \alpha - \beta })^{2} = {( \frac{ - b}{a}) }^{2} - 4 \times \frac{c}{a}$

Hence

$\alpha - \beta = \sqrt{( \frac{ - b}{a} ) {}^{2} - 4 \times \frac{c}{a} }$
