Answer 1

Answer:

Step-by-step explanation:

==> In the given equation ,

p(x) = 4x² + 3x + 7

And α = alpha , β = beta are the zeroes of the given polynomial.

We have to find the value of ,

1/α + 1/β

We have the following values -

a = 4

b = 3

c = 7

We know that,

α + β = -b/a

= -3/4

Also we know that,

αβ = c/a

= 7/4

Now, by using the identity of a quadratic expression,[ 1/α + 1/β = α+β/αβ ]

By putting the obtained value we get,

1/α + 1/β = α+β/αβ

= -3/7

Therefore 1/α + 1/β = -3/7

Hope this will Help you. GOOD LUCK!!
