You want to know the probability of getting one of these 22 cards
                                                       J♥ Q♥ K♥
                                                       J♦ Q♦ K♦

That's 22 out of 52, which we make into a fraction which reduces to 22/52 which reduces it to 11/26

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
