Solving quadratic equations by factorisation

A quadratic equation is of the form $a{x}^2+bx+c=0$ where $a\ne 0$.

1. 1

   A quadratic equation is of the form $a{x}^2+bx+c=0$ where $a\ne 0$.

2. 2

   Factorisation involves expressing the quadratic as a product of two linear factors.

3. 3

   If $(x-p)(x-q)=0$, then $x=p$ or $x=q$.

4. 4

   This method is efficient when factors are easily identifiable.
