In this lesson, we will write quadratic equations when given the roots of the function. We will discuss that any pair of roots actually yields an infinite family of quadratic functions that pass through those roots.
We discuss what this actually means, how to find the family of functions, and how to find a specific quadratic that passes through those roots. We will also graph these quadratic functions.

From the UK.
They are k(x^2-6x+5)=0 for any non zero k.
In order to make the solution unique, so you need to say "Find a quadratic equation whose coefficient of x^2 is 1 and roots are 1 and 5", for example.
Alpha and Beta .. can you use those two letters for the roots Jason??
Lots of support from Bangladesh π§π©β€β€β€
