Welcome everyone! Great to see you all here. We're starting in 2 minutes. Make sure you have your exercise books ready.

Thabo N.14:01

Ready! I've been practising the examples from last week 📚

Lebo M.14:01

Hi everyone! Quick question before we start — are we covering both methods today?

Zulu (Teacher)14:02

Yes Lebo! We'll cover factorisation first, then the formula method. Both will be on the exam.

Sipho K.14:02

I always mess up the signs when factorising. Hoping today helps!

Amara D.14:03

Same here Sipho 😅

Zulu (Teacher)14:04

Okay, let's begin! I'm sharing my screen now. Can everyone see the equation on the board?

Thabo N.14:04

Yes, clear! 👍

Nomsa P.14:05

I can see it but the text is a bit small on my phone. Could you make it bigger?

Zulu (Teacher)14:05

Good point Nomsa, zooming in now. Better?
