hi I'm new to this kind of stuff so I'll try my best to explain this

well I'm in grade 10 pre cal and I can't seem to understand how to get the x-intercept of a question can u help me??

What's the math problem?

take the equation, set y to 0, calculate x, that is the x intercept.

That's the simplest answer to your question, and is all I can give you without knowing anythign else.
