how do you complete the square with variables?

Solve by completing the square. Assume that a,b, and c are nonzero constants.

x squared + x + c = 0

x squared + bx + c = 0

ax squared + bx + c = 0

and i need help solving these:

square root 2/5 + square root 5/2

(3 radical 2) to the third power

(2i radical 6) to the second power

thank you.
