Answer:
b. a unique real solution
Step-by-step explanation:
A quadratic equation ax² + bx + c = 0 ,
Has two distinct real roots,
If discriminant, ![D=b^2 - 4ac > 1](https://tex.z-dn.net/?f=D%3Db%5E2%20-%204ac%20%3E%201)
Has two equal real roots,
If D = 0,
Has two imaginary roots or no real roots,
if D < 1,
Here. the given qudratic equation,
![4x^2 + 32x + 64=0](https://tex.z-dn.net/?f=4x%5E2%20%2B%2032x%20%2B%2064%3D0)
By comparing,
a = 4, b = 32, c = 64,
![\implies D = 32^2 - 4\times 4\times 64 = 1024 - 1024 = 0](https://tex.z-dn.net/?f=%5Cimplies%20D%20%3D%2032%5E2%20-%204%5Ctimes%204%5Ctimes%2064%20%3D%201024%20-%201024%20%3D%200)
Hence, the equation has two equal real roots or a unique real solution.
i.e. OPTION 'b' is correct.
