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 *x*^{2} – 4 (difference of 2 squares) and *x*^{2}
+ 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.
