The best way to solve any complex problem is to start off by formulating a general overview of the problem. This is useful as it allows you to see the overall 'big' picture and allows you to really compre...

(x+4)(x+3) 

From the question you need to write out all the multiples of the coefficient of x, in this case:

1 and 12, 2 and 6, 3 and 4. The numbers in the brackets have to also add up to th...

Using integration by parts, answer = 1/4x⁴lnx - 1/16x⁴ + C

For any equation in the form ax^2+bx+c and a=1, the first step is to find a set of numbers. In this case, they must add up to 8 (b) and multiply to 15 (c). 

With trial and error, it can be found th...

What does this inequality sign mean? That A "is greater than" B.

We can treat inequalities as if they are = signs as long as we don't multiply or divide by negative numbers. What would ha...
