ALGEBRA | Factorising and Solving Quadratic Equations: The Factoring Method or Quadratic Formula (Part I)

It is a pity to see many students shying away from enjoying maths. Students often find certain topics like Algebra challenging. I’d like to identify the difference between simple and complex quadratic equations and solve them as examples. The questions are real GCSE (UK/Edexcel) exam questions

To solve a quadratic equation (equation of the highest power of 2), one MUST first know how to factorise the equation.

Factorising and solving simple quadratic expressions (and equations) like x2 – 4 (difference of 2 squares) and x2 + 4x + 4 can be easy. But such this work, introduced in Grade 9 or 10, often paves way for harder questions in later years. So a proper understanding is vital.
