Which of the following is the correct ratio for the angle bisector theorem for this triangle?

Solve for x -2.3(r - 1.2 ) = -9.66 enter you answer as decimal.

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
