We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:

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
The answer is C or 12 because it has to equal to 180 so 5(12) + 5 = 65 and 65 + 115 = 180
Answer:
