Aquadratic equation of the form 0 = ax2 + bx + c has one real number solution. which could be the equation? 0 = 2x2 – 4x + 1 0 = 2x2 – 5x + 3 0 = –2x2 – 4x – 2 0 = –2x2 – 3x – 1

Step-by-step explanation:

To solve this problem we must calculate the discriminant of each quadratic function.

Let be a quadratic function with a, b and c their real coefficients, then:

If the function has 2 real solutions.

If the function has 1 double real solution

If the function has complex solutions.

Now we calculate the discriminant for each of the functions:

(Two real solutions)
