Question

Dicriminant of x² – 49 = 0

Answer 1

196

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.
