Question

If α & β are the zeroes of 2x² +5x + 1,then the value of α + β +αβ = ​

Answer 1

Step-by-step explanation:

$\alpha \beta = \frac{1}{2} \\ \\ \alpha + \beta = \frac{ - 5}{2} \\ \\ \alpha \beta + \alpha + \beta = \frac{1}{2} + \frac{ - 5}{2} \\ \\ = \frac{1 - 5}{2} \\ \\ = \frac{ - 4}{2} \\ \\ - 2$
