Question

how many real solutions does $4x^2 - 3x + 1 = 0$ have?
○ 0 real solutions but 2 complex solutions
○ 2 real solutions
○ 1 real solution

Explanation:

Step1: Recall discriminant formula

For quadratic equation \(ax^2 + bx + c = 0\), discriminant \(D = b^2 - 4ac\).
Here, \(a = 4\), \(b = -3\), \(c = 1\).

Step2: Calculate discriminant

Substitute values: \(D = (-3)^2 - 4\times4\times1 = 9 - 16 = -7\).

Step3: Analyze discriminant

Since \(D < 0\), quadratic has 0 real solutions and 2 complex solutions (by quadratic formula properties).

Answer:

A. 0 real solutions but 2 complex solutions
