use the discriminant to determine whether the following equation have solutions that are : two different rational solutions : two different irrational solutions : exactly one rational solution : or two different imaginary solutions


  • MATH - ,

    rearrange to the more usual form:

    5z^2 + 8z + 7 = 0
    the discriminant is 8^2-4*5*7 < 0

    So, what does that tell you about the roots?
