To determine how many real solutions the quadratic equation \(4x^2 + x + 3 = 0\) has, we can use the discriminant, which is calculated from the coefficients of the quadratic equation in the form \(ax^2 + bx + c = 0\). The discriminant is given by:

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

For the equation \(4x^2 + x + 3 = 0\):

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

Now, we calculate the discriminant:

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

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

Therefore, the correct response is:

no real solutions
