Answer:

x=5, x=-17/5

Step-by-step explanation:

x=integer

5x-8=  ...is eight less than five times another product

=85

So our equation is x·(5x-8)=85

Steps:

distribute x

5x^2-8x=85

Subtract 85 to create a quadratic equation

5x^2-8x-85=0

Now I"ll upload the work that's shown in Symbolab because it's neater than my own work-

Hope I helped, have a nice day :)
