Question

solveee this plssss I'll mark you as the brainliest answer ​

Answer 1

Step-by-step explanation:

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

= -5

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

= -k

Now,

According to question

$\alpha - \beta = 1$

SOBS

${ \alpha }^{2} + { \beta }^{2} - 2 \alpha \beta = 1$

${ (\alpha + \beta )}^{2} - 4 \alpha \beta = 1$

25+4k=1

4k=-24

k=-6
