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...
