Can someone help me with this question? Use the discriminant to determine whether the following equations have solutions that are:two different rational solutions: two different irrational solutions: exactly one rational solution: or two different imaginary solutions.
s^25s6=0

the discriminant is b^2  4ac
= 25  4(1)(6) = 49
which is a perfect square , so the square root part will come out exact,
so you will have 2 different rational roots.
