Perhaps if you show some effort in trying to solve these problems, a tutor may be able to help you.
I suppose by "disciminant" you mean the term b^2 - 4ac. To find out what a, b and c are, rewrite the equati9n in the form
ax^2 + bx + c = 0
That means a=7, b=-2 and c=5. That makes discriminant a large negative number. The two roots are imaginary.
