When we factorise, we do so to make the expression more simple. Factorising is when we take common factors from the expression and group them together, and then multiply these common factors by somethi...

p(x)=x³+2x²-5x-6

      =x(x²+2x-5)-6

      =x(x²+2x+1-6)-6 as we know (x+1)²=x²+2x+1,5 can be expressed 1-6...

Because the highest power of X is 2, this is a Quadratic Equation

When factorised, these look like 

       (x + a)(x + b)                 where a & b ar...

Mutations in genetic code occur naturally leading to different alleles in genes. (1 mark)

This leads to variation within a species. (1 m...

Show clearly that (3√3)² = 27

First of all, the question looks overfacing due to the surds, I can assure you that surds are not scary, they simply act as a means of clea...
