Manipulation Of Quadratic Expressions
Gbogbo ọrọ náà
Quadratic expressions appear everywhere in mathematics, from modelling projectile trajectories to optimising areas and profits. Mastering the art of reshaping them through factorisation and completing the square gives you direct access to a quadratic's roots, vertex and symmetry, all without reaching for the formula.
In this topic you will learn two powerful rewriting techniques: factorising a quadratic into a product of linear factors and completing the square to reveal the turning point. Both are essential tools for the rest of the 4PM1 course and appear frequently in Edexcel exam questions.
