hope this helps! i got 100 on the quiz on edge
Your formula for this is
![9^{2} =x(24+x)](https://tex.z-dn.net/?f=%209%5E%7B2%7D%20%3Dx%2824%2Bx%29)
and
![81=24x+ x^{2}](https://tex.z-dn.net/?f=81%3D24x%2B%20x%5E%7B2%7D%20)
. Get everything on one side of the equals sign, set it equal to 0 and factor. When you do this you get (x-3)(x+27). The Zero Product Property rule tells us that either x-3 = 0 or x+27 = 0 and that x = 3 and -27. The only thing in math that will NEVER be negative besides time is distance/length, therefore, x cannot be 27 and has to be 3.
