Question

If α and β are the roots of the equations 2x^2 +7x+3=0,find the value of (1/α+1/β)​

Answer 1

Answer:

-7/3

Step-by-step explanation:

1/alpha+1/beta=alpha+beta/alpha*beta

We know that for a quadratic equation,

Alpha+beta=-b/a=-7/2

Alpha*beta=c/a=3/2

So by substituting

-7/2 / 3/2=-7/3

Answer 2

Answer:

alpha=-3 & beta=-1/2

value of 1/alpha + 1/beta= -7/3
