How to get intersection points of two graphs?

Hey guys,
I want to get the x-intercept of my curve (i.e. the root of f(x) as a value). Since desmos doesn’t give results upto many decimal points (say 7 to 8), I require it in this much decimal points. Is there a way?
I have attached a photo for a reference


You can get a bit more accuracy from using the regression (~) feature, but still not to 7 or 8 d.p. I don’t think there is any way to get that level of accuracy out of Desmos.
