Hi SuperbKumquat1712,

Thank you for your question!

The first step in this problem is to factor each term in the equation, for example, you can factor x^2-16 in (x-4)(x+4). You'll need to do this for each quadratic equation, most of the factors that you'll obtain will cancel each other out. Finally, you'll need to find the value of ? to get an expression that is equal to 1/5. To find it, try to find a term that cancels everything, and then multiply it by a value that will get the equation equals to 1/5.

I hope it helps and feel free to write to us again if you have any other questions!
