Thurs 9th March – Algebra – Solving equations – From simple to Quadratic Equations

LEARNING
OBJECTIVE: Revise and extend skills in algebra to solve equations

SUCCESS
CRITERIA: You will be able to solve equations using algebra of these difficulties

1. Simple equations (unknown on one side only)
   
2. Expanding brackets and simplifying
   
3. Unknown on both sides
   
4. Expand brackets on either side of equality and then simplify and solve
   
5. Equations with x² in them – Quadratics that will factorise
   
6. Equations that are written as fractions
   
7. The difference of two squares type problems
   

ENGAGEMENT
ACTIVITY:

Can you solve these equations:

1. 5x + 4 = 19
   
2. 6x + 3 = 4x + 23
   
3. 3(2x-3) = 5(1-3x)
   
4. x² - 4x + 12
   

LESSON: Discuss answers to above questions, and revise skills needed to solve them.
