First find the discriminant. The formula for it is
D = b^2 - 4ac
D = 3^2 - 4(-7)(-4)
Solve that, and if the solution is positive, there are 2 solutions.
If it's negative, there are imaginary solutions.
If it equals 0, there is one solution
For the following equation, state the value of the discriminant and then describe the nature of the solutions.
-7x^2+3x-4=0
What is the value of the disriminant?
Does the equation have two imaginary solutions, two real solutions, or one real solution?
