To determine the number of real solutions for the quadratic equation \(4x^2 + x + 3 = 0\), we can use the discriminant \(D\), which is given by the formula:

\[ D = b^2 - 4ac \]

For the quadratic equation \(ax^2 + bx + c = 0\), we have:

  • \(a = 4\)
  • \(b = 1\)
  • \(c = 3\)

Now, we calculate the discriminant:

\[ D = (1)^2 - 4(4)(3) \] \[ D = 1 - 48 \] \[ D = -47 \]

Since the discriminant \(D\) is negative (\(-47 < 0\)), this indicates that the quadratic equation has no real solutions.

Thus, the correct answer is:

no real solutions.
