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 something to ...

p(x)=x 3 +2x 2 -5x-6 =x(x 2 +2x-5)-6 =x(x 2 +2x+1-6)-6 as we know (x+1) 2 =x 2 +2x+1,5 can be expressed 1-6 =x[(x+1) 2 -6]-6 =x(x+1) 2 -6x-6 =x(x+1) 2 -6(x+1) =(x+1)[x(x+1)-6] =(x+1)(x 2 +x-6) here, -6 can b...

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 are constants To factorise this, we need to find 2 numbers which add together...

Mutations in genetic code occur naturally leading to different alleles in genes. (1 mark) This leads to variation within a species. (1 mark) Variation provides some individuals with traits which mean they ar...
