What are the zeros of the quadratic function if it doesn't cross the x-axis

Since a 0 the parabola opens up (is U shaped). Since the roots are imaginary the parabola has no x-intercepts.

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 *_*
