Answer:
a = ±1/2
Step-by-step explanation:
Given a quadratic polynomial such that,
Also, it's given that,
The zereos are equal.
Let the zeroes be 'm'.
Now, we know that,
Sum of zereos = -b/a
=> m + m = -1/a
=> 2m = -1/a .......(1)
Also, we know that,
Product of zereos = c/a
=> m × m = a/a
=> m^2 = 1
=> m = ±1
Substituting this value in (1), we get,
=> 2(±1) = -1/a
=> ±2 = -1/a
=> -1/a = ±2
=> a = -1/±2
=> a = -(±1)/2
=> a = ±1/2
Hence, required value of a = ±1/2
