Answer:

  zero

Step-by-step explanation:

The answer to that question is best found by looking at the value of the discriminant.

For quadratic ax^2 +bx +c = 0, the value of the discriminant is ...

  d = b^2 -4ac

Here, you have a=3, b=8, c=7, so the discriminant is ...

  d = 8^2 -4(3)(7) = 64 -84 = -20

When the discriminant is negative, both solutions are complex (not real).

There are zero real solutions to this equation.
