Answer:

196

Step-by-step explanation:

The discriminant (Δ) is given by:

$\Delta = b^2-4ac$

Where the polynomial is in the form:

$ax^2+bx+c=0$

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

$\Delta = 0^2-4(1)(-49) = -(-196) = 196$

Thus, the discriminant of x² – 49 = 0 is 196.
