A well set up differentiated lesson on using the formula. As a footnote I added some further questions and got my students to vote on their solving method for each eg, Square, Formula or Factorise!

Lovely, thank you. I really like the idea of practising finding a, b and c first. There is an error however on the red answers at the beginning
