Same Q, different time: Binomials, trinomials? Differences of squares, differences of cubes? Are there certain steps for any of these? Any easy formulas that will make it so much easier? I freaking hate them!... Thanks for all the help, I appreciate it :)

(X^2-X^2)=(X^2-X^2)
(DIFFERENCE BETWEEN 2 SQUARES)(X-X)(X+X)=(TAKE A COMMON FACTOR)X(X-X)
DIVIDE BOTH SIDES BY (X-X)

I am a homeschooled A Level Math student... I study maths 3-4 hours everyday, on top of my other 5 A level subjects.

So Apart from practice, what other good methods are there for learning maths??

x/2 < 2/3 (x+3)

the x/2 and 2/3 are fractions. This problem is under Solving Inequalities with variables on both sides of the equation. I came up with the answer x >-0.444 and my dad tried it and he came up with x > -12

If you come up with an answer please show how you did it so i can see what happened. It's kinda complicated considering I have the hardest time with fractions in equations. I'd appreciate the help! Thanks guys!

NO! The thing said I deleted my question when in reality I did no such thing. I've seen it happen on other forums but I though Yahoo would be better than this. PS, even though upon further examantion my conclution was false, the answer was not, in fact 50*25. Good try though.
