The discriminant is part of the quadratic formula. If the value of the discriminant is less than 0, you have 2 imaginary solutions; if the discriminant is equal to 0, you have 1 real solution; if the discriminant is greater than 0, you have 2 real solutions.
The discriminant is , which for us, looks like this:
which simplifies to -63. That means that the solutions are imaginary...not real at all. So in answer to your question, there are no real zeros at all.

Step-by-step explanation:
We are given the following information in the question:
Number of cards in a deck = 52
Formula:
a) P(Heart or Diamond)
Total number of hearts and diamonds in a deck = 13 + 13 = 26
P( Heart or Diamond) =
b) P(Heart or Diamond or Spade)
Total number of hearts, diamonds and spades in a deck = 13 + 13 + 13 = 39
P( Heart or Diamond or Spades) =
c) P(10 or Spades)
Total number of spades in a deck = 13
Number of 10 in a deck = 4
P( 10 or Spades) =
