Factorising quadratic expressions is the opposite of multiplying out the brackets. For example the expression (x+1)(x+3) can be multiplied out to give x^2+4x+3. Going the other way or reversing this process is called factorising.
The ability to factorise quadratic functions is essential to making sound progress in advanced mathematics. It is a skill. You get better with practise.
