Answer 2

Answer:

Sum = 4

Product = -3

Step-by-step explanation:

As per the given question,

The given polynomial is

$2x^{2}-8x-6$

Let α and β be the zeroes of any polynomial.

Therefore,

We know that the sum of zeroes is given by

α + β = -b/a

And product is given by

α × β = c/a

From the given polynomial,

a  = 2

b = -8

c = -6

Therefore,

$\alpha + \beta = \frac{-b}{a} = \frac{8}{2} =4 \\\alpha \times \beta=\frac{c}{a} =\frac{-6}{2} = -3$

Hence, the sum and product of zeroes of polynomials 4 and -3 respectively.
