You mean to say that we have to find x intercept?
Where are you having problem??
Ok so just put y =0 :
Not the answer you are looking for? Search for more explanations.
For finding x intercept we put y = 0..
Oh okay, sry I forgot about that and yeah had trouble factoring it and now I see. This means our x= -8 and 5/3
Right, I'd also like to add that in case you forget whether to make the y or the x zero when it comes to either intercept remember that any x-intercept would have to be (x, 0) and that any y-intercept would have to be (0, y). Cheers
