Find a quadratic polynomial the sum and the product of whose zeroes are respectively the given numbers.
Let the two zeroes be a and b.
The generalized form of the quadratic equation with sum and product of zeroes a and b is as follows:
ax2 + bx + c = 0 ………………… (i)
Now in this case
∴ a + b = -b/a = 0
∴ ab = c/a = √5
If a = k, where k is any real number,
b = 0 ………………… (ii)
c = √5k ………………… (iii)
Put values from (ii) and (iii) in (i)
kx2 + (0)x + (√5k) = 0
k (x2 + √5) = 0
Therefore the quadratic equation is as follows:
x2 + √5 = 0
