This covers how to factorise quadratics written in the form ax2+bx+c into two brackets, where the expression will factorise. The quadratic formula and completing the square are covered separately.

Mr Hegarty gives a thorough breakdown of factorising quadratics as the reverse process of expanding double brackets, a subject he has covered in a previous video.

Nancy's gentle pace allows learners to be eased into this subject. She looks at basic quadratics as well as those with a coefficient of x2 that may or may not be easily factorised at the start. Not only does Nancy show us how to factorise quadratics in this video, she also covers how each quadratic can be solved, although this is covered in a separate topic area. If you want to make a distinction between factorising and solving, you will notice that the quadratics in this video are = to something, so this means that once factorised, they can be solved.

Yay Math takes us through how to factorise a quadratic when it has no 'x' term, something we know as the difference of two squares.
