*The Quadratic Formula can be used to
solve any Quadratic equation. But, students must know how to use it; they must
know values of a, b, & c; know their directed numbers; and know how to
simplify surds.

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.
