The formula to find the discriminant equals D = b^2-4ac.
(Quadratic equations have the formula ax^2+bx+c. A = -1, B = +4, C = -2.)
D = 4^2-4(-1)(-2). 8-8 = 0.
0 = 1 solution
-D = 0 solutions
+D = 2 solutions
The discriminant equals 0, also establishing that if you were asked to find the solutions, there would only be one.
The answer would be 7.564
Here is the work and next to it I checked the answer
Answer:
B
Step-by-step explanation:
Both C and D solve the equations, so the system must have infinite solutions.
