Kelly has 1/ 14 hours to complete 3 chores before leaving for soccer practice. If she spends an equal amount of time on each chore, which of the following could Kelly use to find the part of an hour each chore will require?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
