Answer:

196

Step-by-step explanation:

The discriminant (Δ) is given by:

[tex]\Delta = b^2-4ac[/tex]

Where the polynomial is in the form:

[tex]ax^2+bx+c=0[/tex]

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

[tex]\Delta = 0^2-4(1)(-49) = -(-196) = 196[/tex]

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