  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

hey

#

so you're doing everything right up until this step

#

Honestly i've never seen anyone do this, why dont you just bring all of the terms to one side and solve a quadratic equation?

#

I believe that there isnt, because when I solve the quadratic, I get the answer that there are no real solutions

#

And even if there is a way, just bringing the terms to one side and solving a quadratic is the easiest way

#

So solve -3x^2 - 10x - 21 = 0 (multiply both sides by -1 to make it easier) -> 3x^2 + 10x + 21 = 0
