**Students often find certain topics like Algebra challenging. I’d like to identify the difference between**

*and solve them as examples. The questions are real GCSE (UK/Edexcel) exam questions.*__simple and complex quadratic equations__
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

Factorising and solving simple quadratic expressions (and
equations) like

**(difference of 2 squares) and***x*^{2}– 4**can be easy.***x*^{2}+ 4x + 4But such this work, introduced in Grade 9 or
10, often paves way for harder questions in later years.

See the illustrations below on how to solve quadratic equations. You can relate these examples to the questions your teachers set for you.

## Solving Simple Quadratic Equations

## Factoring Method or Quadratic Formula (Part I)

The factoring method is introduced early in Year 7 and covered extensively in the later years at secondary schools.

## More on Solving Complex Quadratic Equations

Find out either to Factorise and solve or use the Quadratic formula in Part (II)
