Plzzzzzzzzzzzzzzzzzzzzzzzzz will give brainliest

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 many 2/5s are in 1 and 1/2 plz someone me right now
