Thank you for the opportunity to help you with your question!

7p2 = -24p

First put into standard form:

7p2 + 24p = 0

Now use quadratic formula

-(24) +/- sqrt(24^2 - 4(7)(0)) / 2(7)

-24 +/- 24 / 14

p = 0

p = -48/14 = -24/7

therefore, the solution set is {-24/7, 0}

Please let me know if you need any clarification. I'm always happy to answer your questions.
