Solving quadratic equations by factorising
Topic Notes
Review the chapter on "Factoring" to refresh your memory if you don't quite remember how to factor polynomials. It will definitely help you solve the questions in this lesson!
Difference of Squares:
Basic Concepts
- Factoring polynomials:
- Factoring perfect square trinomials: (a + b)^2 = a^2 + 2ab + b^2 or (a - b)^2 = a^2 - 2ab + b^2
- Find the difference of squares: (a - b)(a + b) = (a^2 - b^2)
- Solving polynomial equations
