8 Solving by factorising TVWO 3
What you need:
- Textbook, writingbook, Tablet, Phone - Pen, pencil, Calculator
Slide 1 - Tekstslide
Lesson goals
Solve equations with factorisation.
Factorize a difference of two squares.
Slide 2 - Tekstslide
A x B = 0
In this case A = 0 or B = 0
A quadratic equation that is not written in the form A x B = 0, can be solved by factorising.
