Solve for the smallest integral value of k if the roots of the equation x^2+10x+k=0 are imaginary
I've simplified it down to (a/3a+1)+(3/4(a^2-1)) but I don't know if I did right first step because I'm not sure where to go next.
Two sidea and an angle are given. Determine whether the given information results in no triangle, one triangle, or two triangle. a=4 b=3 B=15degrees
