I need help with these three problems. They are on a Study Guide and I need some refreshing up of how to do them.

17. Solve the equation using the zero product property...

-8n(5n+3)

19. Solve the equation by factoring

5z^2-2z-3=0

20. Solve the equation by completing the square..

x^-3x=4

Thank you.. Please show me how you did it if possible.

17 is not an equation.

19. What terms give a product of -3 and add 5 of one and one of the other to give -2?

20. Is there a typo in this question?

I hope this helps. Thanks for asking.
