Posted by on .

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.

  • math - ,

    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.
