Solve.
m/9 = 8
a m = 1.1
b m = 17
c m = 27
d m = 72

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

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?
