Objective: To introduce basic algebraic expressions and formulae
Subtopics to be covered:
- Expansion of (a+b)2 ,(a-b)2 , (a+b)2 + (a-b)2 , (a+b)2 - (a-b)2 , (a+b)(a-b)
- Expansion of (a+b+c)2
- Solve expressions based of these formula
- Solve expressions involving numbers by using any of the above formula
Learning Outcome:
- Students can simplify the expressions by using any of the formula above
