Factoring quadratics (scientific method)
Factoring a quadratic equation means decomposing a polynomial into the product of its binomials. We did invent an algorithm to find any possible factoring. Three important steps are combined to find a solution:
- Equating coefficients to create a system of linear equations
- Solve that system of linear equations
- Use the pq formula to get the final variable
There are infinite possibilities so that a limitation had to be built in. B is always a natural number.

Video-Einführung
To understand the whole process it is necessary to deal with the applied methods.
Shaelene Stranges provides a quick and clean tutorial how equating coefficients works.
The second method is the solving of a system of linear equations by substitution. Khan Academy made a great video to explain this topic. It also provides some extra examples for a comprehensive understanding.
The last method is the pq formula. Solving Math (hey, that’s me!) provides everything you need to know about it here.
