Factorising quadratics - (easy)

(The third of three ways to solve (find the roots) of quadratics)

We know factors are found using ladders, and we know quadratics have an `x^2`  term.

 

To factor a general quadratic formula as

`x^2+bx+c=0`

Use ladders as follows:

NOTE:

Find factors of `c`  that add to give `b`.
