Please answer this.​

Answer 1

Answer:

Step-by-step explanation:

α and β are zeros of

2x²-x+5

Thus

$\alpha +\beta = \frac 12 \ and \ \alpha \beta =\frac 52\\\\\Rightarrow \alpha ^ {-1}+ \beta ^ {-1}\\\\=\frac 1\alpha + \frac 1\beta\\\\=\frac{\alpha +\beta}{\alpha \beta} \\\\=\frac{\frac12}{\frac 52} \\\\=\frac12 \times \frac25\\\\\bf=\frac15$
