Solve by using quadratic formula: 3y -2=y^2+5y-4 show steps

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

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

Aline passes through 3,7 and 6,9 what equation represents the line
