Question

Sum and product of the zeroes of polynomial x2-3 are respectively

Answer 1

Answer:

0,-3

Step-by-step explanation:

Recall the identity

a 2

b 2

(a−

b)(a+

b)

.

Using it, we can write :

x 2

3=

(x−

3

)(x+

3

)

.

So, the value of

x 2

3

is zero when

x=

3

or x=

−

3

.

Therefore, the zeroes of

x 2

3

are

3

and

−

3

Now, sum of zeroes

=

3

−

3

=

0

product of zeroes

=

(

3

)(−

3

)=

−3
