Explanation:
The discriminant of a quadratic is the expression inside the radical of the quadratic formula.
b^2−4 (ac)
Substitute in the values of a, b, and c.
1^2 − 4 (4 x 3)
Evaluate the result to find the discriminant.
Simplify each term.
One to any power is one.
1 − 4 (4 x 3)
Multiply
−4 (4 x 3)
Subtract 48 from 1.
