Final answer:
The student asked for cosecant of an angle which is unrelated to the provided quadratic equations content. The correct method involves trigonometric identities or calculations, not the quadratic formula.
Step-by-step explanation:
The question 'Find the Exact Value csc(20/12)' seems to be misplaced within content related to solving quadratic equations. The correct mathematical process for finding the exact value of the cosecant of an angle is not related to the given quadratic equation expressions. Normally, if we wanted to evaluate csc(20/12), which is the reciprocal of the sine function, we would first convert it to a familiar angle measure, use a unit circle, trigonometric identities, or calculators if the exact value is not readily known from common angles. However, the information provided seems to be irrelevant to the question asked as it pertains to quadratic equations, not trigonometric functions.
