Answer:
mark me brainlest pleaseeee
Step-by-step explanation:
We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:
![x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B-b%2B-%20%5Csqrt%7B%20b%5E%7B2%7D%20-4ac%7D%20%7D%7B2a%7D%20)
b = coefficient of x term = 12
a = coefficient of squared term = 4
c = constant term = 9
Using the values, we get:
So, the correct answer to this question is option B
