Huh? So what did you put for it? Wait, it just means solve for x doesn't it?

There are no girls in music.

Water has very strong hydrogen bonds (intermolecular forces) due the large difference in electronegavities of hydrogen (2.2) and oxygen (3.5). This means it would be unfavourable for water to break it's intermolecular forces and form intermolecular forces with another substances as the strength...

PDHPE I think. It will depend on examination results.

Listing is simply providing a set of terms about a certain topic, one after the other. For example: Australia is coastal, urban, suburban, rural, mountainous and geographically-isolated.

I'm in year 11 but I'm aiming for 95% in mathematics and 80% in extension 1 for these upcoming prelim exams.

Re: inequation The denominator with the variable (x) in it is ALWAYS a factor when you are solving (I think).

Cumulative detail is similar to descriptive language. The difference is it concentrates on describing one thing in alot of detail, thus the imagery of a particular thing accumulates (is continually building up) in the responder's mind. Correct me if I'm wrong english academics.

Re: inequation The first equation i.e. the question.

Re: inequation 2/(2-x) > 3 2(2-x) = 3(2-x)2 4-2x = 3(4-4x+x2) 3x2 - 10x + 8 = 0 x = 4/3, 2 Sub in x = 0 1 > 3 False But 2-x cannot equal 0. Therefore x cannot be 2. Therefore, 4/3 < x < 2

Cumulative detail is one technique, listing is another.

cos(3x+2x) = cos3xcos2x - sin3xsin2x = [cos(2x+x) . (cos2x - sin2x)] - [sin(2x+x) . 2sinxcosx] = [cos2xcosx - sin2xsinx . (cos2x - sin2x)] - [(sin2xcosx + cos2xsinx) . 2sinxcosx] = {[(cos2x - sin2x) cosx - 2sinxcosx] . [cos2x - sin2x]} - {[2sinxcosx + (cos2x - sin2x) sinx] . 2sinxcosx}...

I can relate. I've been putting in heaps of work but I am severely under-prepared for my exams starting in 5 days (despite the fact I do ALL the work and more)! :( I think I'll fail chemistry and PDHPE.

I've decided to do extension 2 maths. :) We'll see how I go. Should be a good challenge.

As tommykins showed, reduce the equation to a quadratic by making a substitution. That it the safest way to do it I reckon.
