Well my ultimate dream is to become a physist. I have some other interests, such as being a pilot (flying a commerial airplane), since my vision is not 20/20 and I cannot fly in the airforce or navy. I also would like to create video games, and the colleage I would go to for that you learn calculus courses. In flying, you must know vectors. It's really all fasinating. But I have trouble with one of the most fundamentals of calculus; factoring. Right now I'm not in school. You see, I went to a charter school (A school which you can go at your own pace, on computers) for a year. I graduated from 11th grade there. I failed the AIMS math test because I got frusterated over material I had no learned yet. (As a freshmen I took pre algebra, as a sohpmore I took algebra and as a junior I took more algebra and geometry). Out of all this algebra, I never was taught factoring, or a good majority of what was on the AIMS math. I do GOOD in math, I've always had A's. I graduated early; and I just moved to surprise arizona, so I am not enrolled in school yet. I'm waiting for 12th grade to start. I was supposed to have to take the math AIMS before I could go on to 12th grade (I failed it) but I moved BEFORE I could retake it. I'm hoping to take trigonmetry but I'm scared I will be behind since I am having alot of trouble factoring. I have a calculus book, and it talks about factoring. It's confusing especially because I don't have a teacher to talk to. My parents are bad at math. How do you factor something using the difference of squares such as: 2x^2 + 10. You can't factor 10, because its not a perfect square. Could someone please give me some examples, including the different types of problems, and then give me some problems, so I can solve them. Thank you. PS: I know I have a long ways to go but I hope to become a physist.
