Question

write the sum and product of the zeroes of polynomial x²-4

Answer 1

Here,  a = 1  ;  b = 0  ;  c = - 4

The product of zeroes of a quadratic polynomial is c/a.

∴ c/a = -4/1= -4

So the product of the zeroes is -4.

Thank you. :-))

Answer 2

Answer:

Step-by-step explanation:

x²-4=0

x²=4

x=±√4

x=+2,-2

sum of two no = -b/a

-2+2=-0/1

0=0

product of two no=c/a

-2×2=-4/1

-4=-4
