The expression 3/6 kids the weight of an object onto the moon in pounds in weight

F(x) = (x^2 + 3x − 4) and g (x) = (x+4) find f/g and state the domain.

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

Which one ? is the answer and how to find this answer
