Question

What is the value of the discriminant for the quadratic equation `4x^2-2x+1=0`?

Answer 1

The discriminant is -12.

Explanation:

The formula for a discriminant is `b^2 - 4ac`. Quadratic equations are usually written in the form `ax^2 + bx + c`. In this case, `a = 4, b = -2, and c = 1`. Substituting the values in the formula is:

`(-2)^2 - 4(4)(1) = 4 - 16 = -12`.
