Answer:
196
Step-by-step explanation:
The discriminant (Δ) is given by:

Where the polynomial is in the form:

In this problem, a = 1, b = 0, and c = -49. Thus, plugging it into the formula:

Thus, the discriminant of x² – 49 = 0 is 196.
I’m pretty sure the answer is C
The third choice is very useful. It's valid because two things that are both equal to 'y' are equal to each other, and it can be easily solved to find 'x'.
