Treat the > as an = and solve the equation as you normally would. So for the inequality 7x+2 > 2x-3, pretend it was 7x+2 = 2x-3 and solve that. Just make sure you always replace where you'd write an...

Not all matrices can be multiplied together, so the first thing to do is check it's even possible! To do this write the matrices next to each other (we'll call the first one A and the second B). If the nu...

There are two ways to solve the equation. One is to simply factorise it and the other is to use the formula provided in the formula booklet. The second method is probably easier when there isn't a nice ea...

You should not be put off by the algebraic letters used, substituting x's for z's is absolutely fine. For the first part of the question, since the equation involves the product of two terms, there are tw...

split the integral into (x^4)/(x^2) and (3x)/(x^2) which becomes x^2 and 3*(1/x). These can now be integrated separately and added together after the integration.

first integral: raise the power fo...
