Answer 1

Answer:

4, i think-

Step-by-step explanation:

Answer 2

Answer

Sum = 4

Product = -3

Step-by-step explanation:

As per the given question,

The given polynomial is

2x^{2}-8x-62x

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,

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

α+β=

a

−b

=

2

8

=4

α×β=

a

c

=

2

−6

=−3

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