x=-4, x=2When you see a quadratic equation like this, the first thing you should try and do is factorise it. You need to find two numbers that add together to make the second term of the equation - in thi...

X=6 X=-3This simple question is the fundamental step of a vest argebra topics. Having a good understanding of this topic is crucial to studens who want to do well. Alternative method is to use quadratic f...

We want to get the the sqrt(27) and sqrt(192) so that they have the same number in the square so they can then be added together. We will look at the factorisation of 27, 192. We can see 27 is divisible b...

The answer should always end with x = …, so we need to rearrange and simplify the equation to solve this.First write out the full equation: x + 1 = x/2 + 4Multiply everything by 2 to remove the fraction: ...

as ln x is not a standard integral given in the formula booklet, but it’s derivative is a standard derivative, you can split ln x into 1 times ln x. This allows you to use the integral product rule method...
